Not fixing service

I logged a call that my line is not working on the 1st of April - 11CTK010415. Received a noticed the next day that it will be assigned to a technician, but to date no progress was made. I've escalated the call via Telkom's web application as I can't get through to the call center - On Friday I phoned for 1 and a 1/2 hours without my call being answered. On my cell it is pretty expensive to do so. Please I need this resolved asap as my lively-hood depends on it.
