Useless Service from customer support at Vodacom

I have spent an hour trying to speak to a human at customer support just to find out why my balance on the Vodacom app does not reflect the airtime I bought on the 4th May. I have gone round in circles for an hour with their useless automated system. At one stage a woman answered but I could not hear her as there were many people shouting in the background. She then hung up.!!!!! Useless service.
