Beware of cancellation due to bad service

I was with Cartrack previously and bought a new vehicle. My broker told me I need a tracking device for hijacking and theft. I had it install soon after. I was later told by my broker that the tracking device Cartrack installed is not acceptable by my insurance and need to upgrade to a "fleet management tracking system". I phoned Cartrack at Menlyn Pretoria and also went to see them to make arrangements. My broker also sent them an email to contact me for the upgrade. Please note I do not have insurance cover if I do not do the upgrade. After two weeks out of desperation I contacted Tracker and had a new tracking device installed the following day. The day after Cartrack contacted me to do an upgrade. I told them it is not needed as I am now with Tracker. I contacted Cartrack to cancel my Cartrack contract as they do not get back to me for the upgrade for two weeks while I do not have insurance cover. They told me I am welcome to cancel the contract, but there will be an immediate cancellation fee payable of R3,000. Really? For service I didn't get? I contact my broker and he said he will take it up with the Regional Manager at Cartrack to get this sorted. The manager never contacted me. It is now six weeks later and I am now paying for two tracking device. Well done Cartrack!! Be warned.
