No Customer service, un authorised deductions!!!

I am extremely disappointed in the service that I have been receiving from Nedbank! first mega type nonsense deducts money from my account without my permission! secondly I phone Nedbank, I hold on the line for 10 minutes, the consultant picks up and drops the line!!! this is unacceptable please guys man no! is there anyone that is willing to help and assist me before my next pay date and more money gets deducted that I don't have! I thought I have a savings account with you guys? clearly its not the case!
