Cartrack

My wife bought a car in 2020 then we approached cartrack to install car track device in her car,everything went well up untill she was involved in a terrable excident where by a car was a write off.We approched cartrack to stop a contract as we no longer have a car surprisingly they still deducting money from her account till today.We still dont understand how possible you are paying for something you dont use anymore,this is a day light ******* and no one on their side want to assist us on this matter,we have been contacting them with no success,we urge cartrack to contact us with regards as we are not happy about their service
