CarTrack RipOfffff

I am a CarTrack customer trying to downgrade to a lower offer as I can't afford the R265 (increasing to R291) monthly premium. I called in yesterday to enquire and was told that if I want to downgrade, I would have to pay a once off fee of R350 on top of my monthly lower premium. When I asked why, Gabriel- the consultant, told me that he also doesn't know what the R350 is for as it is not as though I am asking for a reinstallation of the tracking device. I am highly disappointed!
