AT&T has locked my cell phone and refuses to unlock it. Salesmen in-store and customer service failed to disclose to me their policy of requiring service for 6 months until after I purchased service with another carrier but couldn't use it because my phone was locked. This lack of disclosure about the 6-month service requirement has caused me significant distress and financial inconvenience. I meet the requirements listed on their website to unlock it. I requested an unlock but the male tech support refuses, was rude and he yelled at me. The store employees said I will have to purchase another wireless phone. I have a family and have been without cellular service for a week and customer service knew my intention to end prepaid service with AT&T and I've paid for service with another carrier but can't use it. It took hours to reach anyone and I had big problems initially starting service which should have been a red flag.
