Bad service - STAY AWAY!!!

I've been a customer with Netstar for around 10 Years now. I've been threatening several times to take my business away because they service sucks bigtime. However, I thought, let me give them one more try on a new vehicle I purchased for my wife. BIG mistake!!! I have Netstar tracking devices in two of my vehicles. One for my vehicle and one for my wife. It's been 3 weeks now that I've been struggling to get these idiots to update their system with the correct info of the person to be called. I have called their call center several times, I also called their emergency room, wrote them emails. I've even update the incorrect details on the Portal myself. Still not luck. They simply cannot do a simple task of updating their system to call the correct person in case of emergency. They keep on calling me for me for my wife's car. Furthermore, when they signed up the new device, they made a mistake on the certificate with the vehicle model. That has not been changed either and my insurance does not want to accept the details as it is currently. My next step is to cancel my contract and log an incident with the Ombudsman!
