Useless customer care

I have ordered a brand new sim only contract 2 weeks ago from Vodacom. I have received the sim via the courier company. My number was supposed to be ported to the vodacom sim card. I have both old and new sim in my fone for more than a week, but the new sim is not activated yet. I have phone vodacoms customer care, activation and after service department, but no one can help me. Sometimes they just transfer the call without saying anything or keep me on the line for over 5min. I am a new client and it seems they don't need new business. This is very frustrating. I moved from another service provider because of vad service and now it seems its even worse at Vodacom
