TELKOM IS USELESS

I AM READY TO PULL MY HAIR OUT. My elderly parents landline was replaced by a new wireless landline with a SIM card. Telkom delivered the new phone to them and cut their landline the same day. THIS WAS ABOUT TWO MONTHS AGO. Between now and then I have been messed around by TELKOM so much it is actually not even believable. The long and the short of it is that the SIM CARD on the new phone has never been activated despite numerous ( im talking like 20) calls to technical support assuring me the SIM would be valid within 48 hours. I have had numerous reasons given. The first was just that they needed to activate the SIM card and it would take 48 hours. Made that call at 48 hour periods for about two weeks with NO SUCESS. Was then informed by a telkom call agent that in fact i needed to go into a TELKOM shop to get the SIM replaced and get a new one which i duly did - with my elderly 80 year old mother in tow- only be told the sim could not be replaced unless it had been activated which it hadn't. She gave me the number of the technical support specialists on ***. Once again i was assured on multiple occasions that the SIM would be activated within 48 hours and given reference numbers. This went on for about 6 weeks. I was then informed at some point the order had not been actioned. I provided them the order number and waited the obligatory 48 hours- NOTHING.More calls and still nothing. More reference numbers and nothing. Yesterday i was informed that i must call 10213 again because the landline had been migrated ( this was confirmed on one system) but the SIM CARD did not even appear on the new system? this seems inconsistent with previous interactions where i believed the SIM card could be seen but in fact had not been activated. I tried the online help system today and they could not help me either - i was told to call 10213 to activate the SIM. I AM AT MY WITS END I have two elderly parents who rely on their landline for everything and absolutely no help from TELKOM in resolving this issue. IT IS SHOCKING AND UNBELIEVABLE that i have not yet found ONE person to assist me.
