Shocking Service / Bad Attitude- Sim Swap

Went to Vodacom Shop in Hyde Park Shopping Centre to do a SIM swap on Sunday Morning at 09h30. The first request was made for a micro sim - it was then found that I needed a nano sim. The request for the micro sim was cancelled and the nano sim requested on the system. The system apparently wouldn't allow her to activate the new request. In the interim I had received 4 sms indicating sim swap requests. She told me she would activate it in 90 mins time and my sim would be ready for use in 2 hours time. Well, needless to say nothing happened. On Monday morning I phoned the shop, I no continuously engaged, the other just rang and rang. I phoned Vodacom. after being cut off a few times, I eventually spoke to a consultant at 11h36 who told me that the SIM was activated and that it would be working after 3 hours. At 17h45 I phoned Vodacom, telling them that it was still not working. Only to be told that this SIM was cancelled. That it was never activated and that I have to go back to the shop and get a new SIM card. There is nothing they can do. Speak to the manager at the shop!! And I was told that I should not have been charged for this sim swap?!?!?!? This after I asked!
