Telkom ADSL line unstable for the last 6 months

I am actually so livered with the service we have been receiving from Telkom wrt their ADSL line. About 6 months ago, our ADSL line started playing up - working for a short while, then dropping, then working again, then dropping. <br> <br> This ADSL line we use for our business and as any other company, we rely on emails and the use of technology to keep our business running.<br> <br> Every single time we call Telkom, we are given a reference number, the problem is escalated, the problem is temporarily resolved for an hour or 2 and then we start all over again...<br> <br> In the beginning, the technicians would at least come to the premises to check out the lines etc. but lately we never see any technicians or receive a visit from any Telkom representatives. All we get is an sms informing us that the problem has been resolved and if we agree to reply \yes"or \""no\"" to which we always reply \""no\"". Again we hear nothing from them"
