Netstar customer service as dead as a dodo?

Hi I tried to cancel my Netstar tracking account in September 2020 having bought a new car with a tracking device and emergency SOS activation already included in the vehicle. It took dozens of emails and calls to cancel and eventually it was. I then had two premiums deducted from my account despite the fact that the person who eventually called me to acknowledge the cancellation said there would be no further debits. Many emails and calls later to get these amounts refunded have met with no success. The customer service is shocking and their entire method of dealing with this has been appalling and I would summise **********. I hope someone at Netstar monitors complaints and takes positive action.
