bought an iphone pro 11 at an official At&t store back in 12-1-2019 and traded in an iphone 8 256 plus paid $170 upgrade fee but had an issue with the phone, returned it and the experience at the store was not greatest so I got a refund and the contract canceled and left the store with no phone. Went to bestbuy and purchased another 11pro unlocked purchased on NO contract but put an att sim in it and continued with them..however they still were charging me for the iphone 8 which I do not have possession of, ive called every month since and was told in april 2020 that things were going to be reviewed on my billing and refund the charges for the iphone 8....it's now july 1 2020 and it's still not resolved! anyone else go through this hell????
