SIM CARD Nightmare

I lost my phone on Saturday 7th February 2015. I went to the East Rand Mall branch and they did a SIM SWOP, next day went back. They said it's not 24 hours yet - I MUST WAIT. Nothing happened, so Tuesday I went back to them. They said the request did not go through, they have to re-submit the SIM SWOP again. Already I've lost 2 days of contact on my phone which is also a business phone, and I'm not sure if it is going through to head office now. Just after 16:00 they phoned me to say I must come to their branch so that they can do another SIM SWOP. I said I'll rather go to the branch at Festival Mall as they are closer to me. On Tuesday afternoon I went to the Branch at Festival Mall, explained the whole story and they did a SIM SWOP for me. Wednesday morning arrived and still no activation. After countless calls to 808, I'm not even remotely closer to an answer. Again waited my 24 hours since the SIM SWOP was done. It's now on day 4 without a business phone. They did a re-submit and who knows, maybe I'll have to wait another 24 hours which will make it 5 days without any contact on my business phone - what happens to all the calls I've missed?? The calls I could not make?
