This number showed up on my phone no idea who it is and they don't leave a voicemail, anyone know who this could be???

Glad you posted the information, even if you were first & there was nothing here. This is exactly what criminals & scammers want. Curiosity, which of course, cleaned out the cat's bank account. If you know no one in the (601) area code (Central Mississippi) don't take or call them back. Active/live phone numbers are sold by scammers for between $5. and $7. a sheet.
