said by yyzlhr:And yes, you hit it right on the nail, this is a communications issue. What they offered you is a "CAP" offer. Cashless Adjustment Program. These are offers that give a feature for free for a short period of time and are intended as an alternative to actual credits. These CAP offers will fall off automatically on the expiration date. Unfortunately this was never communicated to you, leaving you to believe that you would simply be charged the regular price after the two month period. Any CSR with any sort of common sense would have been able to piece this together...
It is strange that the offered me a CAP offer when I asked to have my SMS plan upgraded from 500 outgoing messages to unlimited messages and, somehow in the process, I was left with no plan at all and a huge bill.
said by yyzlhr:As for the 411 charges, it's very rare for a customer to be charged for a 411 call that was never initiated. What kind of phone do you have? Perhaps you have an app from a lest than reliable author that is dialling 411 in the background. You can bring this up with the OOP and they may just credit you back as well considering it's only $2.50 if they refuse you can ask them to launch an investigation to prove that the charges are legitimate.
At the time of the 411 charge I had an iPhone 4. More recently, I upgraded to an iPhone 5. There should be no rogue application dialling 411 as it never happened to me before (and I haven't installed any new applications recently).
