Continuous faults

We have continuously been having faults with out Telkom line and unbearably slow internet speeds. We are supposedly on a 4Meg line, (have been charged for a 10Meg line for a long time, but that is another complaint) and we only get under HALF a meg (normally 0.3meg when we can actually get the speedtest website to open). We have logged a fault 4 times now and each time Telkom says they fixed it and it is fine for a short while and then right back to normal. 2 of the technicians that came here say that we need to move the line to the other pole. They give us their \direct cell number"and say that we must get a reference number and phone them and they will come and move the line to the other pole. I've tried so many times to get hold of them but the phone just rings and there is no response to SMS's. So we log another fault and the whole thing starts again. PLEASE send us someone to come and change the cable from the one pole to the other. Until that is done"
