Vodacom - Worst Service Ever at Highveld Mall

Vodacom Highveld Mall (Near Game), First of all.... Please answer your Phones.... Made about 50 calls in last two days to the following nrs, *** and ***. This morning 9h00, somebody answered the phone and said they will call me back. It is now 09h40, still no call. My problem is that i'm trying now from last week Thursday to get my old number porting back to Vodacom, seems nobody knows how to do that at Highveld Mall. I'm using my phone for work and its really annoying not to call from your Vodacom Nr
