Double withdrawal from my bank account

on August 20, 2026 Comcast double withdrew from my bank account my monthly payment. I am on automatic payment and this just runs monthly without my doing anything. I called Thursday night and was told it was a glitch that would be fixed within 24 hours. I called my bank on Friday and they said there was nothing they could do until next week. I called back twice on Friday to speak with supervisors one hung up on me after telling me I was not working with them. The other put me on hold and never came back. I called a third time and was left on hold for an hour. it is now 48 hours and my money is not back and I have checks that are going to bounce because I was not planning on having an additional $400 taken out of my account.  I told them I would have to call the Attorney General. Their response was I am working with them meaning Comcast  At no point have they offered a credit to next month or apologized for inconveniencing us  They are all working from the same script, saying rest assured ma’am only one will be processed. I cannot rest assured as my bank account is out $800 instead of $400.
