New installation since 8th Dec not attended

I App**** for a new broadband internet connection on the 8th December 2015 to date nothing has been done. I continuously receive sms requesting confirmation to set appointments but that is not honoured. A technician only cam once on 21st December and that was the last time I heard of them. I went to the Telkom offices to complain and they only told me that they do not follow the smses as committed dates I should wait for a technician to phone. I went again on 5th Jan 2016 to find out what is happening with my order and they checked the computer and gave me a date of the 8th I told the service guy that they previously that they do not use the system to commit dates and he just ignored me and said that is what is in the system. To date nothing has been done
