Awaiting sim swop for 2 weeks

I cant believe such a Big company as vodacom can be so unprofessionall to such an extent i have been battling to activate my sim as i have requested a sim swop Both via call centre and even went to a vodacom but i am still sitting with a sim card that is inactive everytime i call in i am asked the very same questions and still no service is given its really frustrating as i have had this number for over 8 years and i use it for business this has been going on for two weeks and i am even thinking of porting my as the lack of service from vodacom is really bad and consultants seem not to know what they doing or talking about.
