Telkom Fault Not Getting Fixed

In less than 2 months I have once again reported a fault to Telkom regarding very slow and intermittent internet connectivity - 31CTK090915. I was contacted for the first time on Monday 21/09/15 by a technician with regards to the latest fault report. He installed a new test router to determine where the problem might be, gave me his cell number and told me that he would come back next week Monday. Now we have hardly internet, when we do it is extremely slow and running the office is almost impossible. I received no answer on calling the technician, I then left a message to receive a reply that he is currently on leave and can only help me next week. Simply unacceptable! Almost 2 weeks later and the problem is still not sorted out. I did however received an sms on Monday which stated that this matter has now been resolved. Really???? Can someone please help me????
