Paid for airtime through online banking, didn't get my airtime.

I am rating this good but just have a minor complaint. Things usually go smooth with this bank and online banking. I like the revamp on their site. However, I bought some airtime (R55 vodacom) on their site a month ago. I haven't had time but just bought airtime again and then remembered. The money went off on my bank account, but I never received the airtime on my phone. Might be both parties at fault here but I felt peeved with Absa for taking the money and giving me nothing in return. The transaction was through their site afterall. Had I bought at a shop I would not have had this issue. But they offer the convenience so they need to deliver. R55 is R55.
