Telkom ADSL line intermittant

I am VERY UPSET. <br> Firstly: We are paying for a 4MB/Sec line, but was told that due to the distance we are from the exchange Telkom can only guarentee us 2 MB/sec. This is not acceptable as I am running my business from home. <br> Secondly: Since we have installed our ADSL line a year ago, its been more down than up with last month being the last straw, as it did not work at all despite re-reporting it to Telkom everytime it is so called \fixed". This has resulted in me having a 3g bill of R29"
