Cant receive calls at business for over 1 week

I logged a fault with Telkom on Thursday 1 October 2015. On the 2nd of Oct, I visited the gateway Telkom store to explain that this is a business line and that we cannot receive calls, the incoming line rings twice and is auto answered but we cannot hear the clients on the line. The Telkom agent escalated the fault as urgent. I also requested that they transfer all incoming calls to my cellphone so clients could contact us. I had to apply fo this functionality and was told that I will be charged for every call re-directed at telkom rates. So I'm being chaged to find a tempory fix to a telkom line problem.<br> <br> By Saturday we discovered that the calls were still not being redirected. I called the call center again and forwarded copies of the request to redirect the calls. I followed up with the call center repeatedly from Monday this week and they escaled the fault twice. To date the line has not been repaired. The fault was allocated to a repair tech on Monday but to date no one has arrived to fix the line. <br> <br> This is a business line. Will Telkom re-imburse us for lost business? <br> <br> What options to I have to move to a different service provider?
