Technician a no show

I refer to my previous complaint. Telkom responded and said a technician will be sent, but we are still waiting. The number is *** and the acc holder is my mother Ms YC van Zyl. I refuse to pay the account this month. It was on time as usual, but for 2 months now we have had no phone and hardly any ADSL. We are constantly fighting about who gets to use it - since we cannot use it simultaneously as we were used to. I hope something is going to be done soon!!
