Overraft

I am a proud Nedbank Customer who has ben enjoying the banking relationhip with the bank . I have an overdraft with the bank and in which when I made an application I asked for the reduction of R500 monthly first incident happened on March where the amount was reduced from R10000 to R1000 without even ntifying me . And the following month the amount was again loaded and the overdraft was R8000 and today the amount has been reduced from 8000 TO R1000 and my account is overdrawn I have never experience such a level of poor customer service / treatment I got from Nedbank and I'm even thinking of closing my account with immediate effect I will take my salary somewhere else that's so disappointing. I was really enjoying the relationship with the bank.
