Bad service

I was informed by a friend that they had seen my car being driven by someone else on 26 July 2024. When I tried to locate the vehicle using the Netstar app, I discovered that the app was not working. I reached out to Netstar for assistance in locating the vehicle, but they failed to help me and mentioned that there was a fault with the unit. They said that a technician would be sent for repairs, but no one from Netstar contacted me until I followed up on 29 July 2024. Even then, I was only told that a technician would be dispatched to check. It's clear that customer concerns are not being taken seriously, and when I requested to cancel the service, they suddenly informed me about having a contact. I have lost trust in Netstar and I don't feel that I should have to pay for a service that was not provided.
