Worst services from Home connect.

This is the second time that I am writing in a month. I have been having problems with home connect for the last 3 months in connection with my account. I pay them every month bit they keep suspending my account as they say I am still in arrears. They have now gone into my bank account and took off R791 without my permission. I have spent hours with them trying to sort this out but no one can help.
