Did not help with similar swap

I had purchased a new nano technology sim, called the call centre to do a sim swap and was told that the sim would be activated in 24 hours. Two days later, my sim is still not activated. I called the call centre n was then advised that the sim swap was done at 12pm on Sunday and then the number was deleted at 19:00. I was told to go to a vodashop and they will assist in activating my sim. I had gone to the Vodafone shop today n was told they cannot assist me. I must now call cancellation as the number has been deleted. This run around is irritating me. I just want my old number activated on my news card.
