ADSL Fault

On Wednesday I had intermittent connection, reported it, call reference 871crk060515. Thursday connection 100%. No contact from Telkom because if they called they would know that connection was working. Friday no connection, why, because they dispatched technician who managed to get my connection totally broken. Managed to get through to them before 17h00 friday requesting that the Techician who was at that moment looking at the problem call me - no luck. I have been holding on for 1 hour now on my cell, I carry the costs because they managed to break even my landline. Thembi the call agent who answered was really unfriendly would not even give me her surname. Why do they break something that worked?????
