Paid for a DATA Bundle, yet no DATA was credited to me. Take my money no problem though!

On Saturday evening(5th Oct) I purchased MTN Data on my Nedbank Money App - the money, R99 for a 600Mb Bundle, was deducted from my account, yet I was not credited with the DATA I had purchased. This is ridiculous. So I was forced to the buy another bundle from my account on Sunday, 6th October, R99 for 600Mb and alas, it came off and then I was credited with that bundle, but still no bundle from the money I paid on the Saturday evening (5th Oct). So now I've lost money and got no data and I want this resolved. Phoning 135 doesn't offer the option to speak to an actual person and calling the MTN store, doesn't help me either. They tell me to speak to the Call Centre. This is ridiculous. I would like the data I paid for to be actually given to me and TODAY!
