Card did not refill my phone?

Question

 So I have had a prepaid phone for a few months now, and I decided to add a $20 refill card for the first tiem because I was running low. When I scratched off the silver and put in the pin number, it added the minutes to the front of my phone and sent a text saying it had been renewed. less than a second after seeing it on the screen with the new balance, it dropped back to the old balance and a message had been recieved about the refill being cancelled. I thought maybe because I still had a few minutes left on it so I thought nothing of it. So I let my phone run out and I tried adding them again sicne it didn't automatically update. It said the number was invalid. I want to know why the card won't add the money to my phone. I'm getting extremely frustrated with this because I feel like I'm being cheated out of my money. Does anyone know a way to fix this or what I did wrong?

Answer 1

This was the third time I purchased a card on the website for my usual $30 for 90 days before I lost my previous balance.
But this time it did not credit my phone immediately like it did the previous two times before.  I received the usual next day Federal Express with the usual receipt stating I had bought a card for $30 on Nov. 11. 
I don't use my phone except for emergencies.  When I received a text message that I didn't have any money on my account I went to my verizon website and I was not immediately credited with my purchase.  Since I keep all packaging in the file so I know exactly how things arrive along with all packaging and envelope it came in.
I found at the bottom of the Federal Express folder a $30 card that needed it to be scratched off to get a number.
I never received a refill card with scratch off before.  I just received a receipt that I had bought a card for $30.
I tried calling all the numbers given and even talked to a guy I was transferred to in Colorado who understood the problem BUT STILL COULD NOT GIVE ME BACK THE BALANCE THAT I HAD LOST OF $43. 
I told him that if cards were suppose to have arrived the previous two times and they weren't included WHO IS FRAUDULENTLY SCAMMING THE CARDS SINCE I NEVER PUT IN THE NUMBER THAT CAME WITH THE CARD.
HE COULDN'T EVEN GIVE ME CORPORATE so I could talk to the EDP Auditing department.  {please keep your posts courteous}
Why was I always immediately credited on my account the previous times I never received a card without a number?
No one in customer service even understood the problem. {please keep your posts courteous} My degree is in computer Information systems and even had a course of EDP Auditing. 
Also if you try to buy a card online your billing address cannot be a PO Box which your credit cards will have.  It will put your billing address automatically into the delivery address and then will tell you that it can't be delivered to a PO Box when I put in my street address.
They have a serious computer programming problem with their online website coordinating card payments.  Or maybe they did find the problem and people complained that they didn't get a card, which I should have originally have done when one didn't come in the Federal Express envelope along with the receipt.
They will not give out a real corporate address or the phone number that I could talk to the programming department.
The guy wouldn't give me back my balance of $43 for all the trouble I've gone thru with all the time I was on the phone trying to tell them that the company had a serious problem so that they could fix the problem. 
THEY DON'T CARE THAT THEY RIP PEOPLE OFF!  THERE ISN'T A SINGLE CORPORATION THAT CARES IF THEY RIP PEOPLE OFF.
