Ridiculous Cancelation Fee

I fitted a tracker into my car using CarTrack. I wrote-off this car and got myself another car in 2 months since the incident. I contacted CarTrack to find out what the cost would be to fit it in my new car. I was told I needed to pay a transfer fee (for the transfer from the one car to the other) which seemed reasonably priced, but unfortunately I was too late since the written-off car was already sold by the s****yard. The only choose I had at that moment was to pay out the contract which would have worked out being R1800 and something rand. I couldn't afford to payout the contract at that time. Almost 6 months later I phoned again, thinking that the cancellation fee has gone down since I have been paying the instalment of the contract every month. I spoke to Thapelo who informed me that the contact cancellation fee is R1700. When I asked why it didn't go down much Thapelo told me that the cancellation fee is R1700, even if you had to cancel a month before the contract ended. So I basically am paying instalments which doesn't do nothing to my total contract amount. I just wanted to take the opportunity to warn the public of this cancellation fee since it is extremely unfair.
