Bad service

I am not even sure how to explain my frustration regarding the never ending painful process that I have been through trying to get back my own money from a bank that I have been using for many years. I went to withdrawal my salary from atm the slip said technical problem but the amount was less in my bank account.When I went in to the branch to explain to branch manager what has happened I am told to wait 3 days with attitude and that there was nothing he can do, they will balance the atm,this is not my fault I need my money. I have since decided to change banks as I am sitting with no money .
