AT&T Locked iPhone X

This is unfortunate. This experience has created a huge blight in my opinion of both Apple and AT&T. As they keep passing the buck. I am without the ability to communicate for business and this is costing me money.

Unfortunately, I had purchased the phone months ago and at the time of purchase, I was told this phone was unlocked. I was preparing to leave AT&T as my provider at that time. I am not in any contract nor financial obligation to AT&T for the phone or my plan.

Yes I used that site but I have not gotten any traction to get my service functioning. It seems that AT&T keeps blaming it on Apple and Apple says its not their fault. I guess me as the consumer is the one that pays the price. I am pretty upset that I do not have service. I have tried all day to get them both on the phone together and AT&T will not cooperate to fix the issue.
