Grossly overcharged on my first ever ATT bill.
I just moved to a new state and decided I would give AT&T a shot at providing me with a tv and internet bundle package. It was between att and cox. Well, I am starting to regret my decision. I was sold an internet and tv bundle for $89 dollars a month (similar to cox's bundle price). My first bill came out to $177 dollars. I was told they would waive activation fee as cox was doing the same. On 3/11/2020 I had a online chat conversation with an AT&T employee about the overcharges and he assured me these would be resolved and I would only have to pay the $89. So as he requested I made a payment for only $89 and still 13 days later it shows I am past due the incorrect extra amount. He assured me I should only pay $89 and it would be resolved shortly, thankfully I saved the chat. Can anyone recommend how I should proceed to handle this mistake from At&t? Thanks.
