Service..??? What Service...BAD SERVICE..PAY FOR A SERVICE YOU DO NOT RECIEVE!

I have never been happy with the service i recieved from Matrix / mixtelematics! Ladt year i canceled the one unit after the 2 year contract was over, and requested a intallation on a new vehicle we baught. Although they assure you that the tracking device will be installed at your home, this is not always the case and a very big problem if you stay in a small town like Kriel MP. After months of paying the new tracking device it was finally installed at my home after 4 months of paying the device without having it.! Now i am currently paying for the 1ste device i cancelled. All they can say is they can not assist me as this was done over the phone and no cancellation email was sent. So i asked if they can go back on the recordings( bacause all calls are recorded?) The response was that they will investigate and get back to me..this was the 8th of September. Guss what no one got back to me.. i also did send a cancellation email on the 8th of september. An yet again the end of September I was still paying for the same device. So i send another email as getting hold of the customer care or any other department is a major mission. Today eventully after trying to get a hold of them for 4 hours i got through!! And they told me they only recieved the email on the 30th of september.??? Okey so deciding to forget all the money i paid now for something I DO NOT HAVE!! I just want it to be cancelled.!! But this is not the only issue!! We will be selling one of our current vehicles which has a mixtalematix unit in. Today when i got hold of them i also requested they come to remove the device and once we replace the vehicle reinstall it in the new vehicle as i can not cancel the unit it is still on contrack... they want me to pay a futher R1500 for this service.. i aked to be put through to the manager and i was told to hold the line.. ad guess what the hung up again!!!! Now i would like to cancel everything with this company in dont even want to here the name again and never in my life will I ever advise anyone to use them as you will just loose money and you will pay for a service you do not recieve!!
