Shocking service

I bought tracker contract for 3 vehicles - At the time of purchase i could view my vehicles on my app. 2 weeks ago the changed the system and now i dont see any tracking on the Phone. They told me i need to upgrade for this service. I argues that the reason I purchased the R99 package is cause i could the vehicles. The asked me to refer to the contract which supposed to say this is basic retrieve - but i dont have a contract.. On the 4th I had an accident and on the 6 the Insurance company removed my vehicle from my property - On the 15th I requested tracking on vehicle, and was still tracking as being on my property ,when in fact the vehicle was about 100km from me, I could not cancel any vehicle because the cancellation fee exceeds the amount outstanding for the contract. On the 21st I called them to install an new unit in my new vehicle, an appoint was made for the 23rd - I waited all day on the 23rd and no installation was done. I had to curtail all movements for the weekend because of tracker. This company is only interested in taking your money with out providing a service.
