New ever give your bank account to them!

I've been with Xfinity for about four years. I started with a really good plan. I never financed a phone. I got a good Internet deal, a phone plan, and security system. However, I have three other accounts after promos ran out. They said they would keep them. My phone plan costs $140, with no phones financed at all. Instead, they took out over $300. My bank alerted me that they kept taking more and more money. I called Xfinity and explained that I wanted them to stop auto pay. The woman said she did, but she never did right away. They still took money out. I had to call my bank and block them. This has turned into a nightmare. Now I can’t make a payment because they want my bank account info or no service, or I have to go into the store. I figured out how to pay inside myself. This has been terrible, and now they have the audacity to say I owe them $51 after they already took $256. After they took so much money from me — which is ridiculous — if it weren’t for my bank notifications, I’d probably never realize. I’ve been so busy, I might not have noticed, and I was wondering why my bank account balance was so low. Times are tough, and that money could go to my kids for food, clothes, or anything. Now I can’t even get anyone on the phone. They magically switch you to another department and then hang up. I know it’s not their fault; they’re just doing what they’re told. Avoiding this situation is best — they just keep getting money out of us.
