Absolutely non-existent customer service and incompitance

I paid upfront for a contract. No proof that my tracking device was ever activated despite having a fitment certificate. Netstar has refused to provide proof that the device was ever active, after having it installed a year and a half ago. Dealer principal from where I bought the car has also tried to escalate with netstar from his side and he has also received no feedback. I have asked for my calls to be escalated and no one gets back to me. Non existant customer service. They then told me to pay for a new tracking device! Pathetic service
