5 months later...contract still not cancelled!!!

In June 2015 I opened an unlimited mobile contract (just sim) with Telkom, after finding out that I cannot consume data across MTN and Telkom I cancelled my contract in store (sandton) 2 days later (WELL WITHIN COOL OFF PERIOD).<br> I have now spent 5 months calling the contact centre and being told \It's under investigation". My contract has been suspended and I can literally account for money lost in my business as a result of not being able to use my phone. I keep getting messages telling me that I will be referred to the Credit bureau for non payment BUT I DONT OWE A CENT AS I CANCELLED WITHIN THE COOLOFF PERIOD! <br> <br> Cancel my contract!!!"""
