Worst customer services ever!

I complained last month with Jabba Connect that I did not give them the instruction to debit my banking account on the 15 th of the month as they did. I asked my bank to send back the order. When I received a deposit later in the month once again money was deducted by Jabba Connect. No money was deducted from my banking account as was instructed by myself on the 1 st of the month. Once again money was deducted from my bank account on 15 th this money. How is this possible? after the customer services promised me that my debit order will go through on the 1 st of each month?!!! I want out of this contract as I had to move banking institutions because of this ongoing issue with deducting money from my banking account every time someone is doing a deposit into my banking account.
