Telkom landline out of service

I have a landline at home which have been out of service for the past 2weeks, logged a fault with Telkom and it was said they will attend to the matter in 2 working days, they haven't. My mother uses that line as she is elderly and prefers a landline, but now she can't be contacted because the service has been cut and there is no explanation as to what is happening. I called the call centre with *** and i held for 45 minutes and eventually hung up because they kept repeating the consultants are all busy..for 45minutes! If they can't maintain the servicing of landlines, why don't they just tell us to not bother having them. It hardly works for a full month with no glitches, it's either it can't make outgoing calls or no service , it's a prepaid ,they can't even say it's owing money! Am totally disgusted, i even escalated but still no one has bothered to even contact us!
