Sim Swap a dead mission cannot be reached really at MTN?

I really do not know what I have done wrong to MTN South Africa.I requested for Sim Swap to my old known number several sim cards being told different stories everyday.Some would say wait 2 hours , some say tomorrow it will be fine , some say after weekend it be fine , some say you failed security questions.I was ****** my phone with sim card with number *** , trying to get back my number is really a storm.What can I do.I am using *** a temporary number but I want my number back.Bought several lines , made affidavit , certified my ID but no help.MTN FEEL FOR PLEASE>I DO NOT HAVE MORE MONEY , CAN BUY ONE LAST SIM CARD>WHERE SHOULD I GO???
