I am yet again trying another option to resolve this issue after talking to several customer care representatives. **I have an ATT wireless account (***-***-****) that I have been using since ****. On ****, I ported my number to a business account and purchased an iPhone *S (invoice attached). After * years of using the phone, I upgraded the *S to an iPhone ** in April ****. Since then, I have been trying to unlock the old device *S without any luck.**Meanwhile, I left he company I worked for in Oct, **** and the business (Cognizant Technology Solutions) transferred the account and financial responsibility of ***-***-**** to me on Oct *th. I opened another device unlock request and it was denied again stating the account has to be active for less than ** days.**Device IMEI number: *****************Request number: CUL***************So here is my concern. The account is active since ****. The only change happened was transfer of ownership. The business account has approved to transfer the account to me and the device is fully paid of and old for * years. I really do not think it is reasonable for denying the unlock of the device to me.**And on a side note, the customer service has been terrible and the supervisors who join the chat are often rude. **regards,**Sandhya Vijayan
