Terrible service FNB

I went to deposit my salary today, then the atm took some of the money and returned a few notes. Then I returned the notes and machine just stop gave my card ans slip saying transaction unsuccessful. When to the branch filled out forms and they said I must wait. This is not the firts time and I see how people do not get their money back. Only some of the money was deposited and unsuccessful, but the notes that was stuck in the deposit slot not. Since then I could not get any further assistance but be assure I am going back tomorrow and I want answers and my money. Its my salary and I have things to pay and a household to run.
