Harassing company that lacks good customer service

Cartrack is harassing me with calls and Ayanda (male) consultant was sooo rude towards me. I have been with car track for 8yrs and they have never made me feel important as a client. My car was involved in an accident and was taken to Johannesburg but none of these rude consultantsborthered to call me or any of the recovery team. I reversed their payment last week and to my surprise I'm getting thousand phone calls and emails. It shows how this company is good at chowing people's monies but bad at offering the service. It's been more than 4 hrs since the device is checked and no one cares..as a client you have to follow them for their assistant.
