Poor seevice from Cartrack

Good morning, i am not happy about the service i received from Cartrack. Between the 9th / 10th June 2021 i bought a new car trading it with my old Opel Crossland and i phoned Cartrack to assist me with the installation for the new car cancelling the tracker on the old car. This morning i got an sms that they debited my account for 2 cars and i phoned Cartrack advise as to the reason for the double debit order.

I told Cartrack that i only have the current car which they installed tracker around the 10th if not 11th June 21 and requested a refund for the debit order they took for the old car and it seems like its a problem for them to refund me. I even feel that i need to cancel the current contract with them and now they telling me i'll need to pay around 2K to cancel the new contract. It will be appreciated if someone from Cartrack can sort this matter out as this is unacceptable.
