Bad Service from technical support desk (ADSL)

I app**** for an ADSL upgrade on my landline ages ago. No body makes communication with me, I had to phone the call call center myself to find out that the line was upgrade. Now I buy the router and everything only to find the line is not working / not configured properly. I phoned the call center and they keep saying everything is synching and is fine on their side. I phone multiple time trying to explain that the line is not working, they keep making me look stupid and say it's the router. I went to a telkom store to see if the router was working and there was nothing wrong with it. I then phoned again and only there after a fault was logged and I was promised to receive communication in 2 days saying when the issue will be solved. There was just silence all the way round. I phoned the call centre multiple times again but every time they would say we are escalating the issue, we have escalated the issue but even today I have no indication of when my problem is going to be solved. It feels as if one is being taken for a ride here because I did not choose telkom as my ISP. While at the end of the month I am going to be billed for something I have never used. BAD SERVICE!!!
