NETSTAR FAILED TO PROVIDE ME WITH THE WRITTEN CONTRACT OR RECORDING.

Hi i bought a car in 2019 February, so there was a delay from my insurance company which led me take another insurance while I was trying to solve the problem with my old insurance because you can't take the car out of garage without a insurance. Which led me end up with Oakhurst.... Because it was the cheapest for me without knowledge that I'm putting myself into troubles. The Oakhurst told me that they are going to install a tracking device in my car because it is part of the insurance, and I told them that I'm not going to be with them for a long time because i did not like that insurance company the way they do things. I told them that I'm gonna go back to my insurance just waiting for them to sort out the problem, so I told them nicely that I'm going to cancel this policy. They said to me it is okay but i must carry on paying the netstar car track for a year which I did do that till my car was written off and I told them. Now netstar is coming with the stories that I have a three year contract with them which i don't remember signing or agreed to a three year contract. I asked them nicely last year when they threatened me with credit bureau to send me the written contract or recording that shows that I have agreed to a three year contract with them..... Which they failed to deliver that to me!! Instead they keeps on taking my money from my account without my permission which is wrong what they are doing changing the reference every time just to debit my account. PLEASE NETSTAR PROVIDE ME WITH THE WRITTEN CONTRACT OR RECORDING AND STOP SENDING ME STATEMENTS.
