Router/Internet not working since installation

I had a 4mbps adsl line with uncapped internet package installed on 28 Jan 2016. The internet didn't work until 8 Feb 2016. From 10210 saying that the number***) I was given belongs to a company and that they can't help. When I called the dept that sent activation information (Mpho, ***),they gave me run around and pointing me back to 10210. Eventually,The last technician(8th February) told my wife that there were 2 modems on my line hence no internet connection. He reassured us it was now fixed. Truly when I tested that night, there was internet connection. I started to connect my devices and all seemed well enough.<br> <br> I tried to download some staff and that's when I realized what I'm paying for is not what I'm getting. The downloads did not go higher than 300kbps, not even 10% of the promised quality.<br> <br> I have made over 30 calls to Telkom using a cell phone averaging 30min/call. The website 'speed test ' which I was referred to, says my download speed is 0,89mbps. This is a far from 4mbps I'm paying for. I want this fixed immediately, it's been 4 weeks since I app**** for a service I am not getting. (Who does the 2nd modem belong to, is that not *****)
