Phone number port STILL waiting: INCONVENIENCED!

I opened up a contract with cell c direct last week and requested that my old number be kept with the new contract. after 3 days, my number still hadn't been ported and I spoke to a lovely lady in the call centre regarding my problem. she said that she would escalate my request through to the sales team. I urgently need my old number back for business and I also cannot do any of my online banking since they use the number to verify. This is becoming an urgent matter. Although I appreciate the excellent assistance that I did receive from call centre staff, I am becoming agitated
