Nedbank i deposit money into my account yesterday till now is not reflecting how vele

My heart is broken. Yesterday, I went to the ATM to deposit money into my account, but the money is not reflected in my account even today. I am so frustrated about this. If I could get my money, I would be so stressed. How come this happened? My heart is bleeding. I got the slip from atm Mara Money Dololo. What must I do to get my money back?
