I want my R1400 back Nedbank ASAP!!!

Nedbank is a *****! I got my salary yesterday less with R1400 from what I see on my payslip which was also confirmed by their notification, I called them to ask why in my bank account they deposited a different amount from what they sent me on the bank notification and then they said I must call in again today only to find out that today they have change the amount in the bank statement to correspond with what is on the notification but did not deposit the R1400 that was missing! What an *********** bank with poor customer service!!! I want my money back gaaaaa!
