Worst customer experience with help line

Today bought airtime twice and both times the full amount was deducted claiming that it was for airtime advance. I bought R55, it was decuted, I then bought R29 because I urgently needed to make a call but it was also decuted. I called the customer care line, what a waste of my time asking ridiculous questions. I have smses from vodacom confirming that I bout the airtime, the call center lady tells me they can't see a record of me buying airtime today. Vodacom is the worst when coming to resolving client queries. Horrible!!!!!!
