Cartrack debiting me multiple times

Cartrack is debiting me multiple times after i terminated one policy or took off one car from my policy . They created multiple cancelllations leading to multiple debit orders. I have called them many times where i was assured that i would only be debited for a normal instalment as i paid off the cancellation fee. Till today, 3 months later they are still playing in my account.

Im really frustrated by this treatment from Cartrack
