Xfinty mobel

I have have Xfinity for about 7 1/2 years now this year we decided to try there mobile service…. At first we had issues trying to receive are phone took for try’s until we got it fixed an received are phones ok no problem it was fixed a few months went by we had auto pay witch was working out fine until I fell behind a bit so they said we can put you on a payment plan 51 extra a month on top of your 266 ok fine no problem that works I told them hey I get paid once a month due to social security can u take out the payment and repayment on the 10 of dec the guy said sure that’s not a problem ok great the 10 came by and they took out 51 for repayment the receipt says. It my mind they took the whole payment I was thinking awesome well today the 18 they turn off our phones and still no e mail till after the fact the phones were off hmmmm ok I called they said the trying taking out the payment and it failed I look at my bank I still had 275 in there I called the bank they said Xfinity only took out once for 51 and nothing else was attempted or taken out for 266 ok I called Xfinity I was explaining what was going on and told them what was going on and they have told me each time it was a comport are and there nothing we can do!! We are sorry it was our fault but we can’t help u unless u pay 800 an something. So why am I being punished because of a computer error that’s not right I wasn’t told this by one person but 5 different agents it was there fault but nothing we can do about it.. so my wife tryed talking to someone on mobile chat about it this guy had the audacity to sexually harasse here saying if he takes her out for coffee and Japan food he will fix it ummm how unprofessional is that and degrating is that so if anyone can help please do so

thank you for your time
