Exploited by PAYD

I have been with PAYD since 2010, no claims during this period. On inception I was told I will have a Drive Mate device to collect mileage. In 2014 I was told that the unit was unreliable, I need to fit in a Skytrax unit, which I did. PAYD discounted my monthly premium to subsidize the additional cost for Tracker. I get a msg to say that there's no activity on my vehicle, after calling Tracker I was told that I need to pay R550 to have it checked by a tech. I called PAYD to ask why I need to maintain the device that assists them collect data. I was told that if I don't repair the device, PAYD will move my policy to an unlimited option which is R260 more than my current inst. I have asked the Cust Reps for assistance Waheeda &amp
