Netsar ripoff

I have had a Netstar tracker in a number of my cars, and when I sold my car in September 2022 I e mailed Netstar customer service on 27 October 2022 and gave notice of cancellation of my contract which was a month to month contract. I did receive a response to my mail noting that I would receive call from cancellations….. nothing. After numerous mails and calls no response, but they kept taking my debit order! Bunch of *******! After contacting them again with no response I am now waging a public name & shame campaign!
