Shocking service

I am at my wits end. I simply have not experienced worse service from anyone, ever. It has been going on for 3 months. I have made countless calls , sent 6 separate mails to Samkelisiwe, one to Penny and Mfundo was copied at the Ballito branch), spoken to people in the Ballito store (same people) countless times and I am not any closer to resolving the issue. Telkom installed uncapped Fibre at our home and we are paying for 100mbps and our speed is so slow we can hardly load a video (1.01 mbps download and 3.13 upload). They also charged us for the device we were supposed to get with the contract, and the some we got with the contract does not work. So I am essentially not getting anything I paid for. The staff just log another call back then I go to the store. Then I get a call, explain everything, they promise to send someone out and nothing happens. I would like to cancel my contract and go to a private company but even that seems to be a black hole where I am not sure what I would have to pay in if I do. It's really shocking.
