Poor service, Lack of service

Sold my car, can't get ahold of Netsar to remove the device from the vehicle and fit to the new vehicle. Called and on hold for 30 min or more, telling you to use the whatapp bot. I have emailed also and stiil waiting for a consultant to call me back. This is not the first time i am struggling with Netstar. my unit is faulty and they were ment to send someone to look at it and still waiting and it has been 2 months now. Takes the money but does not deliver the service paid for.
