Harassment and terrible service by car track

On the 24th of July I called car track and cancelled my subscription after I been with them for almost 5 years , I spoke to a guy called Wonder who told me it was possible to cancel telephonically although I would be billed for the month - which I was ohk with.

For the past few months I have been harassed by car track and they are ********y debiting from my account. I requested for the call for that day as it is my right but I am still waiting.

I feel like my rights were violated and I should not be billed for a service I am not using after I canceled more than once.
