Cancellation

I have tried to cancel my subscription going on 4 months now. I have spent more than R500 in airtime calling them logging tickets emails etc. I have since been debited 3 x R699 for something I haven’t been using. The modem has been in my garage since the cancellation. I have to approach a lawyer now as this is still not resolved I have numerous reference numbers for the calls. The last being *** . @rain when are you going to stop *****ing money? What more do I need to do before you cancel my subscription?
