Pathetic turnaround time

I have done a dispute on my bank account and usually have to wait 48 hours for my funds to reflect. Money account is telling me now I have to wait an additional 2 to 10 working days because they have a backlog and thats the turnaround time. I banked with Nedbank before this and the minute i walk out the bank my money reflects in my account. I refuse to wait an additional 48hours from today. This is not a realistic turnaround time as a bank. 48hrs isnt even realistic. Have this matter resolved today. If you wanna be a bank, start catching up with the turnaround times of the others. The benefits are fantastic but such complications will let you loose lots of clients especially a valuable one like me who has been with you guys forever.
