Telkom not resolving my query, 5 months later!

I took a Telkom contract on end of September 2015 with the hope of getting what was promised. I was told for R99 a month I would get 100 anynet minutes, unlimited Telkom to Telkom mobile calls, 1GB of Data and free CLI. After taking up the contract I was told I need to pay a monthly fee for CLI (really?), I got 150MB of Data instead of 1GB so I went to the Cresta Branch to cancel since it was within the 5 days of the cool down period. My contract is still not cancelled and they have resolved my issue 3 times saying number already on prepaid even though it was still on contract. It's been 5 months and am still being charged and the calls are coming in as private numbers since CLI is not activated. this is really frustrating and I'm starting to lose patience. Telkom also has a tendency of replying when you post on Hello Peter but when you reply back they don't get back to you! Please cancel this contract ASAP!
