Cartrack service

Cartrack service is *******. For more than a month I have been trying to get out a technician to sort out the issue with the tracker on my vehicle. The last week has been a major inconvenience for me as the tracker has been draining my battery. I reported it immediately and informed them that I need the vehicle as I'm self-employed and the vehicle is used daily so they must please send out a technician. It's a week later and my bakkie is standing in the road, I can't start it and every time I call cartrack their staff is not very helpful or they drop the call midway into the conversation. This is bad service for a company that has such a big national footprint!
