Pathetic service from customer care and product department

I bought my car in 2020 and installed the Netstar unit a week after I bought my car, since then my profile was mixed with someone I don't know, I have sent numerous emails, calls and after 3 years of follow ups, Kgaogelo assisted me. That's close to nothing this unit is timeously interferring with my car power transmission where the car would stop in motion because it cannot power the engine, the pathetic customer service and product departments fail to dispatch their *********** technician to remove the unit, since the dealership can't do it. As I'm writing this review my car has been to the dealership for 2 weeks they have done all their diagnostics and there is nothing wrong with the car but the tracker unit.
