Bongi Mofomate

My vehicle was installed with a tracking device and an installation certificate was provided to me. I paid upfront for the installation fees and the contract within my loan agreement. When I now enquire about my travel logs I am told that my contract was cancelled in November due to me not answering my phone to change ownership. I have requested from Car Track who authorised the cancellation of the service as they are not the ones paying for the service and I cannot get an answer. I have asked the fitment centre what other methods did they try to get hold of me and they do not an an answer. I would like to be refunded the full cost of installation as the tracking device is not working and has been s****ped.
