Telkom basestation now down for over a week now

Hi its been almost 2 weeks the basestation has been off in Chatsworth Malmesberry. I logged a case and my case was deleted and had to log a 2nd case. Its been more then 72 hours and a technician has not been dispatched to fix the issue. This is my case numbers ***9(this one is closed) and this is new one ***4. I want to cancel my contract as I'm paying for something I'm not using. Im not sure who can get this issue resolved.
