72 hours passed, SlM swap not active

Requested a SIM SWAP on the morning of the 2nd of January at Foschini Westgate mall and until today, my Sim card is still not working. Called the call centre to confirm if it had indeed been loaded and was told it was and that I needed to wait 24 to 48 hours but until now there's been nothing. That is my main number that I use for my business and cannot afford to have it off for this long. Sent through a callback request yesterday but this was not honoured. I have had a very good relationship with one2one until now. Please sort this out urgently!!!!!
