Very dissapointed (for the second time)

First off Xfinity doesnt care about customers, just wallets. Ive had Xfinity two times, once for 5 years pre covid, and now (i will be cancling again). I dropped Xfinity during covid when their "unlimited" data stated charging when we were forced to stay at home. They did this without letting customers know. I went to AT&T Fiber. Then recently they brought some great deals. I switched back for internet, added streaming and was fixing to add mobile. When I signed up i used the ACH draft (only way to make their services cheaper than others). I accidently put a few numbers wrong when siging up. They took the deals away. When i called to see what the issue was they said payment was sent back. I called my bank who told me the issue and even offered to talk on my behalf to Xfinity to vouch i had the funds just wrong account number. When i explained this to Xfinity i was told nothing they would do about it and i would be blocked from ACH for 6 months, which makes them double the price of everyone. So i will be cancling them, again.
