Never give your bank account to them

I terminated two of my contracts with them. I didn’t even have contracts. I was paying over $200 for phones that weren’t needed. They were paid off for I was paying for two. I was paying at four accounts Internet two I turned off. They still pulled the money from my account and for the phones I had to block it from my bank now I have another bill and they will not take payment from a credit card only bank they told me.
