Today I was depositing some money, went to deposit 240$ cash and put all the bills in, it took them in in a very weird fashion and said it was unable to read them, then didn't return anything back to me. That's the end of it. The bank was closed during the hours I was doing this and wont be open until Monday at 9. (it's saturday now)

Does anyone know how to proceed? I checked my bank activity online, and sure enough the 240 is not there

Wait until Monday at 9 and go to the bank.

The bank branch may not be open, but you can generally phone your bank 24/7. Which you should have done immediately, so they could look at everything.

What can you do, but wait till Monday - then call them.
