Cartrack, good for nothing

I had a cartrack device in my car. The car was written of by insurance in December and towed to a s****yard. I have paid for a device re installation on the 222nd of January. It is now the 5th of March. I have phoned, sent mails etc. but still nothing. The old device certainly will not still be at the towing yard now. Today I phoned and said I would rather cancel and low and behold. I must pay them a cancellation fee of R2600!!! For a service I don't get!!! The contract was broken by them.
