Let me preface this with the fact that everyone we dealt with in the store was great but what followed has been a nightmare of an ordeal-

On January 4th, 2018 I purchased a new iPhone X thru the AT&T store at 252 Broadway in San Diego. AT&T was offering a "buy one get one free" deal for an iPhone 8 which I took them up on and gave that iPhone to my wife. But she decided that she would prefer the larger iPhone 8 Plus so we returned to the AT&T store a few days later and was told that we would only have to pay a $200 upgrade fee to which we agreed.

But AT&T began charging me monthly installments of $31.67 for the full price ($949.99) of the "free" iPhone 8.
I contacted AT&T and explained what was happening and they said I had to take it up with the store manager which I did. I had to go back down to the store to talk with him but he promised that he would get it handled and a credit would soon appear on my account - but it never did.
I contacted AT&T several more times - including the store manager, AT&T's corporate billing department and a several other departments, each time getting an assurance that it would be handled on the next billing cycle but it still has not been resolved.
AT&T has now just charged me for my 10th monthly installment payment!
At this point I have no faith or patience remaining in AT&T getting this resolved and have just filed a complaint with the BBB to try to get intervention and resolution...
