Bad service

I bought a brand new car in 2015 at Toyota and it came with its "package" and one of the package was that I took the car track with Beamie. And I have been paying the premiums religiously for the past 4 years up until I got a call from a consultant from Beamie advising that my contract was about to expire and she wanted to me to reactive it at the less price since I've never used their service before and I have been paying my premier accordingly. I declined the offer and I told her that I wanted out and I wanted the policy to be cancelled. She was not impressed with me because I refused her offer.

And to my surprise the debit order still went on as per usually and I returned them. I then received an SMS advising that my account was in arrears and they will hand it over for collection and I was provided with an account to make a payment. I then logged a request for a call back and I also stated my case and to date no one has bothered to call me. I also called them and explain and I was told I need to speak to cancellation desk, which I did. I've now received a statement stating that they will be debiting for August and I dont understand as to why would they want to do that? I've never used their service even once in the last four years. And I dont see why should I continue wasting my bread money for something I do not need.
