disappointing service from.Nedbank

hi my name is nathan afrikaner ,I'm so disappointed at the lack of service and compassion from nedbank online consultants I ran into an issue at Kinshasa international airport, I had to draw cash from the atm I tried both times and the atm was offline ,I never got cash from the atm but the money was deducted from my account ,I contacted nedbank and spoke with 5 different consultants whereby 2 of them disconnected the call when they couldn't assist me ,I lost a total of R7000 , if it was FNB or ABSA the money would've been returned within 1 day of notice i explained that I'm working and living abroad and that i needed my money ,and the reply i got from nedbank.is that i have to wait 4 to 5 weeks for them.to investigate so why does FNB or ABSA can resolve the issue within 1 day and nedbank 4 to 5 weeks really unacceptable, and the lack of knowledge from their online team is terrible I'm now closing my account with Nedbank and looking at another bank that genuinely cares about their clients
