Vodacom - bad service

I did a sim swap 58 hours ago and I am still waiting to get my service back. The personnel from Vodacom promised that the whole process only takes 4 hours. After several phone calls and a lot of frustration it appears that no one knows what is going on or how their systems work. They still can't tell me when my service will be back on line for me to use my cellular phone. NB: This is a phone that is on contract and I use it for my business and needless to say I am doing no business, because my customers can't get hold of me.
