NO SERVICE JUST EXCUSES

My ADSL Line has run at 8.8mb to 9mb Sync for the last 2 years. Suddenly in the last 2 months Telkom randomly decides to drop my line to below 6mb - no reason. I have logged call after call and actually been told that the distance from my house to the exchange has increased from 4 km to 6km... On the 13th my line went dead - no dial tone, no ADSL. Logged a call. Then I posted on the Telkom Facebook page. All I get is the standard F^&%ing \Your query has been sent to out team for further investigation."and sms's to say \""testing\"" is in progress. I ask for progress reports on Facebook and on the F*&^ed up call centre - \""Your query has been sent to out team for further investigation.\"" and they are busy testing to determine what the fault is.. How long do you idiots have to \""test\"" a dead line? What do you hope to learn"
