Lied to in store, no help on phone
I recently went to an AT&T store to add my mom to my plan. She was coming over from another carrier and also needed a new phone. After much discussion with the associate and help from the manager, we agreed on a method that would let me add her to my grandfathered unlimited data plan and only add about $30 to my monthly plan for the line charge for my mom's phone, including her $1 per month installment plan on her new phone and taxes/fees.
Of course it was too good to be true. When I saw my bill it was more like $130 more than my original bill - from $121 to $254! Needless to say I was confused and angry. My mom is a senior who was paying $45/month for her phone plan before and who had other upgrade options with other carriers. I was trying to help her out and the quoted price seemed great. There's no way I'd agree such a large increase on my own plan.
I called AT&T to see what happened, and couldn't really hear or understand what the rep was saying to me, so I decided to go back to the store instead. A different store associate was helpful this time, but I essentially had no choice but to switch out of my grandfathered unlimited plan to a 9 GB shared plan to make it affordable to have my mom on my plan. (If I didn't have my own phone on a installment contract, I would have walked instead.)
I tried to call AT&T again to dispute the original bill. (The store rep told me she couldn't do anything about the original bill, that I would have to call.) After being told by the phone rep that he probably couldn't do anything to help me, but to wait on hold while he did research, my call was disconnected after wasting about 40 minutes of my time for nothing. I planned to call again but haven't been able to carve out the time to do so, so I hope I can get help here.
I'm angry that I had to drop my grandfathered plan and feel like I was tricked into it. And, I also still have this $200+ bill that I wasn't expecting and can't afford.
I don't understand how the original store associate could lie to my face about the cost and I'm still responsible for the fraudulent charge. Is there anything I can do? Thanks.
