Terrible telkom connection issues that they refuse to fix.

I recently switched ISP to telkom due to issues on my Mweb line. When I was signing up I was assured that by the salesman that I would receive new infrastructure (new cabling) on the sale. I repeatedly asked if this was infact the case and I was repeatedly assured that it was. The telkom tech came out to install and he didn't install any line he just ported the new number to the old line. Now I am paying for two numbers on one line and I'm having terrible connection issues.A technician was dispatched to check the error on my line only for him to leave and say that the team that did the installation need to come back and fix the job they did. The fault was then cleared and I had to call back to get follow up information. They are now refusing to send out the installation team to fix the mistake. Nobody at telkom wants to help me as they now say it is out of their hands. Please stay away from this horrible ISP. I was better off with Mweb and now I'm under contract for two years. Everyone that has handled my account has refused to help me in any way. Terrible service .
