Incapable of simply porting a number

I have been to Vodashop 3 times since last week (twice at Killarney mall and also at Vodashop Nelspruit) to port my prepaid number to Vodacom but that still hasn't happened. Vodacom's 24-hour porting timeline has elapsed (on Monday afternoon) and the number is still not active. I escalated the issue to porting department las night through online chat and again today at Nelspruit Vodashop but still the number is not active and I still don't know why. I call porting simple because in the past when I ported to Telkom it took just one visit to the Telkom store and no more than 24 hours. But with Vodacom it's days and nobody can explain why or bother to give me feedback.
