My recent poor experience with EE, I know will get deleted.

Question

Ok so for nearly 2 years I have been an EE pay monthly customer.
Since January I have been stuck with a 5 pound global minute add on. (mainly because their site and app keeps telling me there's a problem, and I haven't called them to cancel it, I haven't had the time, so it's partly my fault) because I haven't called. Anyways.
For roughly 20 months I have paid my bill on time via direct debit which amounts have always fluctuated, from 52 quid to 130 a month,however the past 2 months I haven't paid by direct debit and paid it late due to changing banks, my direct debit was not moved with switch. Idk why but that's not the issue here.
The issue is the fact that they disconnected my service on the 7th of last month and I called them immediately and was told I owed 161 quid or something. I told them I could make a payment on the 15th, as I was abroad. They said I would need to pay 80.39 or something by the 15th and the rest before the end of the month. The whole conversation took 5 minutes or less. Which was awesome.
As promised I made a payment in my promise date. And then I thought everything was good. Until a week later my service was cut again, this time I called them again and within 5 minutes I had an apology and my service was activated again. And as promised I made my payment on the 30th of the month.
One issue here is that, in order to contact them when your service is suspended you need to go through so many steps because they only connect you to their stupid self payment service and nothing else.
Anyways my main issue comes after the fact that I called them on Tuesday and asked about upgrade options, as I have 1 months left to the end of my contract, I was told that I would have to call back on Friday or Saturday as because I made a payment that day, their system would not allow me to make an upgrade for 3 days.... Fair enough I said. And hang up.
Today I called them again, and I am being told that I can't upgrade for 3 months because I haven't paid my last bill on time, and that 3 months you have to make payments on time....
When i told them, I accept that, but look at my track record. I have paid you every single month on time until I changed my bank and because my bank didn't change the direct debit for some reason I am being punished... The response, sorry nothing we can do, come back in 3 months...
Ridiculous, the IVR their text messages, the representative on Tuesday all kept telling me yes you can upgrade. Why did all they lie?
Further more, nowhere in terms on conditions or fine print does it say anything about 3 months payments.
Finally they shouldn't offer 3 month early upgrade to insurance customers as a benefit because it is not a benefit that the customers can use, it's false advertising.
Oh well, be aware of the games they play, I will be moving to one of their competitors anyway just wanted to see if they would beat an offer I was given by one of their competitors. But clearly they don't want my business.
I am only glad that I haven't ported in two new numbers I got for my business, and hope that they won't come and say, oh sorry your contract is over but we can't port out your number because you haven't paid 3 bills on time. Next month is my last bill you suckers and I'm gone.

Answer 1

Well further more, despite the problems I did and got my upgrade but I wish I hadn't....
For the first time in my life I bought an electronic item via a store rather than using the Internet... That's the worst decision I ever made in my life. As there is no cooling off period.
I got my upgrade. I came home, said finally I can get rid of this stupid signal box I have at my office. Immediately I texted WiFi calling to enable it. But guess what it does not work. After 2 hours of phone calls still nothing....
Ok then i received a cryptic message from my family member abroad and having no apps installed I said let me call them. And guess what.... "calls to this numbers are barred from your account".... That was a wtf minute.
I said let me start installing my apps, I install cash on tap. And guess what another wtf moment." your sim is not compatible" I kinda knew that was going to happen because I noticed the sim not having the letter N when I was at the store...
Next day I go to the same ee store I got the upgrade from and said issue 1. You have given me a non nfc sim. Please give me a nfc replacement. As my old sim was an nfc sim.
Response I get "ee no longer has nfc sims. Cost savings. If you want nfc call 150. I call 150 and ask for a sim to be sent and I'm told sure... Then i say what about calling abroad. Oh you need to pay 50 deposit or sort it out with the store because it was cancelled as par of the upgrade... Thank you bye. I go back into the store. You cancelled my calling abroad. They are asking for 50 quid, I ben a customer for 2 years and had it enabled. Sorry can't do much. Leave it with us (lady that did the upgrade wasn't there) next day I came back and she was like, yes I cancelled it, usually the ask for 100 deposit and most customers dont want to pay for it. My apologies. (because she apologised) I said fine no problem.
Today I was talking to ee for WiFi calling (level 2 tech) he said I will do sim reset, all your services will work, when he said that I told him about my abroad calling issue. That it still shows in y account but it's not working. He said he could enable it. I asked will there be any deposit, he said no. I said ok then please do.
After getting off the phone I login to ee account and boom fireworks (I got a 50 pound charge, due now)....
O call ee again, and am told they can't remove the charge unless they remove calling abroad. But will refer it to their credit department..... I said fine. If they out remove the fee. Doable the option completely. I don't want it. She said most likely the will waive the fee.
Then I asked if she can check her system to see if my sim was sent out already. She says no. I see nothing on my system. Then I said, can you send me a nfc sim. She tells me I can get it at ee store. When I angrily explain to her what ee shop does because they are cheap. She says, sir I can send out a sim. However if I do. You will not have service until you get the sim.
My response this is nothing personal but **bleep** ee, have a wonderful evening and I hang up.
Bottom line is. Here is what I got for being a loyal customer and upgrading to a 24 month contract after my initial 24 month contract.
1) increase in bill for 16 quid a month.
2) 5 quid loyalty discount removed.
3) downgraded to a regular sim, and being told I can't use cash on tap even though my phone is officially compatible with it.
4) can't use WiFi calling because it simply does not work.
5) can't call abroad because ee is stupid.
I seriously wish I had listen to my friend and moved to Vodafone....
Let's see if an ee rep will respond to this and add their two cents to my two cents.
