telkom promise but cannot deliever

Telkom advertised for unlimited and did not make people aware it was only for 6 months, I then wrote a previous story about telkom on Hello Peter and was contacted by the head office who apologize and said I will get unlimited data for my whole contract, I then agreed and when I called the contact center my plan has changed back go 1g and I was unable to buy data as well, I was then advises that the contact center will be unable to assist me and I cannot buy data so I stayed with internet for a few days and did not receive a response from telkom, I was promised unlimited data by telkom head office yet they are unable to provide the service they Promise and Why have a customer care when they Cant provide a service and repeat the same thing over n over this is really annoying and I would like a response from telkom asap. This problem needs to be resolved cause I Cant go on with no internet when I was promised. Whats worst it is Easter weekend and I am unable to use akype or access the internet I want this problem resolved
