Line needs to be investigated

We moved into a new house. The people who lived here previously, had a 4meg line installed, and had no issues with speed. The day before we moved in, they had cancelled their line. Once we moved in, 3 days later, a Telkom technician came to install our lines. However he told us that we can't have a 4 meg line, we have to downgrade to a 2meg line because the exchange server is too far away from us. <br> I want another technician to investigate this. I find it very difficult to believe that the people who lived here previously could have a 4meg line but we can't. I have asked Mweb to investigate this on numerous occasions however I got no feed back, they just tried to sell me fibre optics packages, which are double the price.<br> I want this further investigated or you must change us to the same exchange server which the previous owners of our house was on just a few days before we moved in!
