MTN's network poor service

I'm very disappointed by the poor service I'm receiving at the mtn store in wonderboom Junction. All I wanted was to do a sim swap to my old number after I lost it during *******, I brought in an affidavit and supporting documents on the 29th November 2020 in the morning, was attended for a sim swap and was told I should have my number after 24hrs, it been two day still number. I've been going to the shop on consecutive days, still no assistance. I'm loosing on business and I had gone for work interviews and was expecting call this week, due to this poor service I might loose everything. No one is saying anything yesterday was told the supervisor was absent therefore the sim swaps were not processed. Like really such a well established network, one person is not in, then the whole of SA is on a stand still. All I need is my old number, new number*** my old, the one I want back ***..
