HORRIBLE SUPPORT FROM CARTRACK

I installed car track into a single vehicle to test as they were running a promotion, I was happy so proceeded to a second vehicle as I wanted the same promotion, the sales representative did not tell me this was a 3 year contract on 2nd vehicle. I used them for almost 2 years, I called to cancel as I was Immigrating out of SA and needed to cancel these 2 vehicles, the said they could only cancel one vehicle as the other is on a contract, I mentioned I did not agree to this as I wanted a month to month, after some frustration they said to me they will need to listen to the recording, the clearly said that this will take no longer than 48Hours, its now been 2 months and I am no longer in SA, I have sent numerous email's , at least 10 and called a few times using international call charges, I expressed my frustrations and to date nothing has been done. I HIGHLY ADVISE NOT TO USE CARTRACK UNLESS YOU WANT UNNECCESARY STRESS, IT HAS BEEEN A HORRIBLE EXPEREICE.
