Horrible and *********** customer service

I signed up for Telkom 10mb Fibre line under my name with a new landline number. Somehow Telkom billed my father without having any permission or signed documentation from him. I've tried to have this rectified for the past 3 months. They have now billed my father and I for the Fiber line and are threatening him via text message that they'll send him to the credit bureau. Due to Telkom's mistakes I haven't had my mobile 2GB data enabled and am still waiting for feedback from Thami Hlophe. I get no response whatsoever from Thami. I wish I had never moved to Telkom. Worst service provider in the country and at every opportunity possible, they get it wrong!
