Poor service

I received an email from Netstar saying my tracker is inactive. I requested a callback from them no one called me. I phoned them 2 times & they keep promising that someone would call me so they can install a new tracker. I haven’t received any call to date but they deduct money out of my account every month. First reference 6/04/2023 Dear Client Your enquiry reference number is : CAS-***-P0K6Regards Netstar. Second reference 08/05/2023 Dear Client Your enquiry reference number is : CAS-***-X9N0Regards Netstar. I think I should just cancel & look for another tracker.
