Spectrum/Charter Deducted an authorized amount from my bank account, after I cancelled the auto pay. St Louis, Riverview MO, FL

I cancelled the internet service, returned the equipment, and then tried to cancel the auto pay, but my account had been made inactive and I could not cancel the auto pay. I called and talked to a person and told them numerous times to not deduct anything automatically and to cancel the auto pay. I asked to have my account re-activated so that I could make sure the auto pay was cancelled, but they said they could not do that.

They went ahead and deduted the auto pay amount that I specifically told them not to deduct, because my service had been cancelled. They refused to do anything about it, and they may still deduct the auto pay next month even though I don't have service. I can't stop them, because I have no access to my account to stop the auto pay.
