Port causes number to go missing

I took out a contract 14 Nov and asked to have my current number ported. It is the number I use for all my business dealings. This had not been done and I went to correct it on 21 Nov. Now the number I wanted to port seems to have disappeared into thin air after the lady tried to attach it to my contract sim. My prepaid sim which contained my current number now has a completely different number. The lady promised it would be fixed on Monday. I have not heard from her since. I have phoned customer care numerous times this week and the situation has not been resolved. They now claim that my number does not exist but I have a sms stating that said number is now a Telkom number. Pathetic service and no care attitudes all round
