Netstar are taking us for a ride( making quick buck)

My matter is still not resolved. Today they only sent me the Policy since being with them from 2017 and this year the device was not functionin. I am forced to pay the installment as is for both cars, or I replace it. Which I will do but what happened to the past 7 years? Paying for the sold car? Today I received an sms that Netstar received an alarm for car registration.... And I went on the app to view and the car was at that particular location. What will it take for you to deactivate the tracker for the other car or should I cancell for both cars? You guys are robbing us and this is not playing well for you. I regret changing from Car track to you. I am disappointed. The private chat was nothing satisfactory to me. Cancel the car that I sold or I will inform the buyer that I can still track his car and let's see how he handles this that his every move is watched and might be hijacked because of your non competency and unprofessional service from the beginning.
