No Landline nor ADSL every 2 months

On a regular basis, almost every 2 months, our landline goes dead because some *********** technician cuts us off at the exchange in order to fix up somebody else's line. This is reported on a number of occasions, but as usual no response, except from the IT section to say our ADSL has been fixed!! How can this be when we do not even have a landline that works?!?!?! Every time you phone Telkom they give you a new ref no. as if that then becomes the new date that you reported the fault - how devious and dishonest to have to resort to such tactics. I am going into my 3rd week. Lots of friendly promises, but no real response!! Every time our line is fixed it takes two or more weeks to do so - how pathetic. Then when we are told that a credit will be passed for having had no line, it gets conveniently \forgotten"off my account"
