My payment has been sent electronically from my bank since this account was opened in 2017. All of a sudden they stopped posting my payments to my account in February and have canceled my service three times. I spend countless hours on the phone, submitted proof of payment multiply times via email, and attempted to complete the payment helper form at att.com/paymenthelper (it did not let me upload the proof of payment). Several months of this and multiply fees later and I again do not have service! The billing department managers (Ernie and Pablo) are not helpful and the claims department doesn't talk or email clients. How is this supposed to ever get resolved?
