My daughter received a call from the same number 561-922-7660 with an automated message, identifying itself as Mountain [something garbled] bank and indicating a problem with her account, press 1, etc. She has no such account but out of curiosity (I told her not to do this in the future, just hang up) pressed 1, which ended the call. I've checked and the number/call shows up on her phone record. So far nothing else. What is the purpose of pressing a number and then the call ending?

got this call about my atm card being suspended the name of the bank the call came from was garbled. I checked with my bank and nothing was wrong with my account
