Unstoppable debit order

I'm very disappointed in car track I even had to cancel the subscription because of them not debiting my account for a year then I had to make arrangements to make arrangements to pay for 6000 odd because of some one not capturing my details correctly. So I paid and canceled all 4 cars and funny thing I'm still debited twice since last month even after settling my debt with you. I called to reverse the amount still amount but reversed and still getting debited very u professional. I owe you nothing why you still debiting my account. Even when I call they say they will reverse and still nothing. Called today they can't help me they will escalate. Worst finance department ever. You can't even reverse the debit order.
