Stranded over Thanksgiving with 2 small children!

I will try to keep this short...over the past 5 days I have been on the phone with EIGHT different agents and I lost count after 10 live agents on virtual assistant (which be of assistance is the last thing they did) My husband lost his job twice over the past year, after 27 and half yrs with the same company. We have had quite the hardship this past year. So YES, we had a balance on our account. On Sept 27 I paid $170. On Nov 15th I paid another $280. Leaving me with a $427 balance to which i was under an installment plan. In the early morning hours (2am) of Thanksgiving Nov 28th. My 2 kids and I were traveling to see my parents. I haven't seen them in over a year. They paid for our way there and we would pay for back. I went to get some snacks and drinks for myself...as my children were sleeping and my bank card declined. What? No way. I made sure to sell enough of our belongings to have the money to see my parents. Its in there! Check online...no it's not in there...because Xfinity decided that the total amount due of $427 should be unlawfully taken out of my checking. This was a nonauthorized, not signed up for auto pay illegal removal of funds from my account. This is where the nightmare begins. I was assured 3 times the money would be back in 24hrs. The finance dept denies request for refund because it was an owed amount. So you take money out of people's accounts if they don't owe??? This has been the most aggregous overstep of corporate boundary i have EVER dealt with. I have stated on every other forum, FB page, survey...that Xfinity had til 3pm to make this right or I hit to complaint to the FCC, my financial institution (who is aware of this, but it takes so long to get money back, they said Xfinity can easily give it back to me) AND my father has called their lawyer. A woman and 2 small kids can't go home because Xfinity has to have almost $1,000 in a month out of my $2000 budget. Thanks Xfinity! Company of the year right here! Beyond livid.
