Prepaid to Contract & Sim Swap

Good day... I've been waiting for the past few days for my current cell number (prepaid) to be changed to a contract number in order for my sim swop to be done. I've been messed around for over a week now. Last Friday I was told that I could come in to fetch my phone that I wanted. Friday came and I had to fill out so much paper work and then the document had to be sent to head office. The credit check qas done on Saturday already but I had to phone them on Monday afternoon to ask if it was done. I was told to come in and then I'd get the phone but that wasn't the case. They didn't have the phone but they said they would process the pre to con. Only yesterday did I get the phone but the pre to con still hasnt been done. I was promised it would be done today but it still hasn't!!! What use is the phone without the proper sim? It's for a business contract so I would expect it to have priority! Its a new line which is added to an exisiting business contract (Spectraprint) All documents have been given so why hasn't any of this happened??? Please can it be done ASAP!
