awaiting a sim swap since my upgrade delivery

i received my upgrade on Monday the 13th, called in for a sim swap since the micro sim I have on my old phone is smaller. I was adv of a turnaround time of 2-4 hours that never happened. I called back on Tuesday and was adv that turnaround is 25-48 hours, fair enough assuming that the agent made a mistake in saying 2-4. I awaited and nothing came through. yesterday (Wednesday) at work I get a missed call from the 140 number just around 12:13 I assumed the person would call back but nothing, I called back and was adv that I would be called back by the (George/Josh/Joshua) in an hour and still nothing, I called back at 15:34 and was adv a mail is being sent to Josh/George and still nothing, I assumed that maybe it was late he would call today first thing, still nothing I called back and spoke to Zanele who adv that there is a que, I've been in that que since Monday and I adv her that they rather collect the phone cause I refuse to pay a pro rata for a phone i'm not even using, she adv me of the cust care mail I sent a mail and still awaiting response. I just called now and spoke to Chantel Shabangu requested that I will hold for her TL and she hung up on me while holding. I am angry
