Cancelation fee - not making sense, live *******

My car was awrite-off last year november and you have been debiting me which I understand I never called and cancel the policy. When I call today to cancel, I'm being told about the cancellation fee of R1700 which I don't remember upon taking the contract even if that was communicated, why would this be applicable on my case? its not like I'm moving to the new tracking company. Not happy at all and some needs to advise on this, I can not keep on paying my for tracking service for a ghost car.
