Damage to vehicle and unauthorized deduction

As I'm not receiving any feedback to the mail I've sent, I'm sharing it on Hello Peter:

On April 30, 2018 the amount of R120.05 was deducted from our account and, much to our surprise, on May 15, 2018 a second deduction was made in the amount of R271.93. We called the Bloemfontein branch of Cartrack and were told that as there were not enough funds in our account, a second deduction was made on May 15th. Please find our bank statement for the relevant period attached. As can clearly be seen there were more than enough funds in the account and the first payment of R120.05 went through. The amount of R271.93 + the debit order fee of R3.73 must therefore be refunded to us immediately.

Also, when the tracker was installed, our vehicle was damaged. After many phone calls, an investigation and even a polygraph test, we were told that Cartrack would pay for the damages. No-one called us to let us know what the result of the polygraph test was, we had to once again make several calls to the Bloemfontein branch manager. We were told that quotations would be obtained. This was approximately three weeks ago and we have not had any contact from Cartrack again whatsoever.

The unauthorized deduction made from our banking account was now the last straw and we would like to cancel the contract with immediate effect please. We have not had a pleasant experience with this company at all. The tracker must be removed from our vehicle as soon as possible by a qualified mechanic and under supervision as we do not trust the Cartrack employees who have installed it (the first time the unit was installed incorrectly and the person who came to fix the incorrectly installed unit damaged the vehicle).
