I have been trying to unlock my apple Iphone XR for three weeks now. To say I am furious is an understatement. The phone is paid off and has been for some time. I purchased the phone from At&t in Feb. 2019. In June 2019 the phone was replaced via apple care due to faulty charging port. I have used the phone without interruption since. I have called At&T customer service 12 times now (chat and phone calls) and visited the local store 3 times. My request continues to be denied because the IMEI does not match or is incompatible with AT&T. That makes sense I guess since it is a replacement phone, however, I have been told time and again that it is being sent to the "back office" and have been assured it will be unlocked. It never is. This is illegal as far as I am concerned. AT&T essentially has possession of my phone and refuses to release it. Calling customer service is a fools errand at this point. They are absolutely powerless it seems. WHAT CAN I DO? I will be filing a complaint with the FCC and BBB, but I want my phone unlocked. Any suggestions?
