ABSA will not pay me back!

I purchased 2gig vodacom of Data from the ABSA portal on the 22nd February, the transaction was successful and R249 went off my account. I checked my data balance and nothing had come through. I made contact with Vodacom and they couldn't pick up the transaction on their side. I then laid a complaint with ABSA and was told there was a problem with vodocom prepaid over the weekend, they will investigate and resolve within 72hrs. It is now 11 days later and still nothing from ABSA, everytime I call them I get told that the person handling my complaint (Yolandi/Yolanda) will get back to me with feedback but nothing. I'm extremely disappointed with the service, the money went off my account within seconds but to get it back has to take a ****** life time. Shocking!
