STILL NO REFUND. AGAIN NEDBANK

On Friday, 20 March 2014, I purchased R100 airtime via Internet banking, however no airtime was sent to my phone. I waited the weekend and still nothing. I then contacted Nedbank call centre and the guy told me that he will log the call as I explained that MTN also did not receive an communication from Nedbank regarding the airtime. It was said by Nedbank that the query will take 3 working days to resolve. I called again last week Friday and the guy told me that they would credit my R100. It is now the 27th March and I still haven't heard from Nedbank. This is disgusting. First bad service, high fees and now they don't want to refund my money. The guy told me that many customers that bought airtime from Nedbank had the same issue and they are refunding everyone. Why always the long wait and bad service from Nedbank? This is ridiculous.
