Poor Service from Postnet Waterfall Corner

I went to apply a ******** checks certificate at Postnet Waterfall Corner on Tuesday 02nd September and I paid R360 which is "supposed" to be fast tracked and get it within 5-6 hours which obviously didn't happen. I waited up to 24hrs and still nothing and I called them I was asked to send through my ID number via Whatsapp and they will check for it and no one bothered to look at the WhatsApp messages I sent. I called back again on Thursday the 04th and was told the same thing to send a WhatsApp with my ID number for them to check and get back to me and I did that again and as usual no one bothered to check or at least give me a call back. Up until this day I am still waiting so all I am expecting is my money back so I can go and get this information somewhere else.
