no one understands the service

Nedbank staff have no idea what send imali is and how it works!!!!! i have tried 3 times to withdraw a small amount of R320 and each time was unable to. No reason why, just unable to withdraw. After standing in an insanely long queue for enquiries I was told that they can't help. They asked me to call the call centre. After holding for more than 20minutes, the call was cut off. Eventually a woman by the ATMs came to my aid to tell me that I am unable to withdraw because of the R20 on the amount. And apparently that Branch don't have R20 in their ATMs! This service is pathetic, I really think Nedbank should leave this to the professioals like FNB, where with eWallet u can withdraw any amount of money you want and not forced to withdraw the whole amount but not make provision for cases like this, where I could have just taken out R300 since there are no R20 in the machines! Like really now. Thanks a lot Nedbank for time wasted.
