Worst Service experienced with Cartrack

Probably the worst customer service I’ve ever had. After cancelling my account due to the sale of my vehicle, I have been debited for two months, one of the months I cancelled the debit order and have been billed for that month and to top it off, a cancellation fee. Not only a cancellation but the WORST customer service from the Accounts Department where a lady got aggressive and shouted at me over the phone for requesting the banking details over email for verification purposes. Apparently CarTrack don’t care about their customers and everything must be done their way. Until CarTrack carry out what a customer would like I will not be paying you anything. I was willing before but your poor customer service has made me frustrated with your company.
