Very Bad Service

My tracking device on my vehicle has not been working since March 2023. I was informed via email from Netstar. After a few telephone calls to try and resolve the issue, with no assistance, I decided to reverse the May debit order and surly a few days later their accounts department contacted me. I explained my situation again and still no assistance to resolve the issue only for me to pay for a faulty unit. After a few more calls and emails to the email address sent to me via message in June, I decided to wait for their response. Today 30 October 2023 I received a call once again to pay the cancellation fee for a contract which expire in July 2023, the call center attendant did not care about my unit that never worked since March, he only wanted me to pay.
