Wrong bill sent to my account
I have moved to another country and I called AT&T last month to change my plan to just "park" the number(s) at $10 per month. They have then sent me a bill of $135.85 for the service that I did not avail. My plan has been changed in last billing cycle.
I can also not log in to the account because they send me the code to the line that is temporarily (for 6 months) deactivated.
Please help me by sending an email to my registered account.
Payment due: 06/23/2019
