Telkom billing putrid

I would like to log a formal complaint with telkom. As this is my first step to taking you guys to the ombudsman. You guys are continuously debiting my account despite me canceling the contract numerous times. You have adversely updated my credit bureau because of this. You have caused such inconvenience in my life. The cherry on top is you guys make it virtually impossible to contact you and to resolve my queries hence I opted to log this complaint. If I am not refunded and my name is not cleared I will definitely go to the ombudsman!!!
