Material Breach of Contract and Unfair Billing

I am writing this to warn others about the lack of service from CarTrack. I cancelled my contract in December because CarTrack failed to provide the security services I was paying for.

On multiple occasions, I tested the system. Even when I didn't answer my phone during simulated signal jams or when I explicitly told them my car was not with me and asked them to investigate, there was no recovery response. They breached our contract by failing to deliver the very security they promised.

Despite this, they are demanding a cancellation fee and continue to bill me. My balance has gone from 1431 rand in January to 1631 rand this month. I have explained this every time they call, yet the harassment for non-payment continues. I refuse to pay a cancellation fee for a service that did not work when it mattered most
