I am struggling with them since last year October 2024 when I asked them to install a tracking device in my car the MAHINDRA XUV500 , 2.2 Diesel on the 12 October 2024, where I signed a contract with a subscription fee starting from 15 November 2024 for amount of R419.00 .I found out that documents were sent to their finance office on two different dates .Now they separated the installment into two installments R220.00 but they calling me almost everyday for their mistake and that I am in error with R220.00 this happens everymonth. I have reported it to my legal team Law FOR ALL and we had a telephonic conversation the three of us with my lawyer where cartrack was supposed to investigate the matter but until now nothing but they keep on calling me to make a payment which I refused to do.Cartrack must get their house in order because everytime they call I told them the same thing.So their service is poor.
