IMMEDIATE PAYMENT? - NO PAYMENT YET 4 DAYS LATER!

COMPLAINT!!!!

On Tuesday 11th June i made a immediate payment to my mom. Received a sms on both side it was successful. The money left my account and she ever received it on her side (Nedbank). When i called Absa they said the money should reflect during the course of the day and it was successfully transferred on their side. Thursday morning my mom went to the bank (Nedbank) they told her there is no money reflecting in her account and that it is Absa's responsibility to tell me where the money is. Called ABSA, but with no luck they said the money did go thru. On Wednesday, I was told Nedbank has a issue with 'immediate' payments and i have to wait till Friday which is absolutely ridiculous! Now they say they can't reverse the transaction and they have to investigate. It has now been 3 DAYS after an immediate payment????? I now see it as being ********** on ABSA side. I have been receiving very little correspondence as to when I am getting my money back, every time i just receive a call 'oh i have just sent you an email on the update' ....what is an email going to do regarding my almost 15k ABSA?? now the long weekend is approaching at that makes it almost a week for an immediate payment to reflect??
