Being billed wrongly!!

Question

I changed my cell phone family plan minutes from 700 to 1400 during the past month knowing that I was going to go over this month. I was exactly at 700 minutes in my plan when I spoke to a customer service rep online and made this change.
I got prorated without being warned about any secret charges Verizon would sneak up on me.
My overall minutes did not exceed 1400 or even 900 if they prorate both plans from the change date. But I got charged $111 overage minutes. I would have definitely stopped my minutes from increasing, had I known this is what they would do!
Ofcourse Verizon has an explanation for this. But for all practical purposes I feel cheated. I paid for 1400 minutes of time, did not go over 1400 minutes and yet am getting overtime minute bills!! I have paid every bill on time in the past. But the first chance that they get to jip me, they take it.
I am at the end of my contract. NO WAY that I am going to get tied into another 2 year contract with them.

Don't you think the Customer Service Rep should have warned me about this? She actually confirmed that I can change the plan this way, and I checked with her every step of the way to make sure nothing was being missed and that this would avoid overage charges. Even if I had not changed my plan at all I would not have gone over by 250 minutes and had to pay over $100 in overage charges. Why would I make a change that would require me to pay more? I contacted the service rep to reduce the possibility and number of overage charges, not increase them.
Of course I can not prove what the service rep said, only Verizon has those records. Also, I understand what the fine print says somewhere and I understand EXACTLY how I was misled. I find it to be very underhand. Just because a con follows a well thought-out paper trail of fine print does not make it a right or legitimate way to do business. That is what a CON is!
I am glad you are sympathetic with the tricks of the trade. If I don't get a sympathetic supervisor, then this will definitely end in a cancellation of service. I am not sympathetic. 
Verizon is too big to care I suppose!
Thanks!

Unless YOU specifically ask to have the new plan BACKDATED, proration will occur.This is how all cell companies handle plan changes.
So if you switched on the 15th day of your billing period, you would have overages if you used more than 350  minutes the first 15 days or over 700 minutes the last 15 days.
Unfortunately unless you find a sympathetic supervisor, you will be responsible for the charges.
