Who called from 7205040037

Called it back and it said this number is not in service. Must be spoofed.

7205040037 has been calling me all day, no one is there and the number not in service

Caller left no message

this is a spoofed number which showed on my id window as:  V607110521000519
I wonder why they think anyone would answer a number like that?  When I used the edit feature on my panasonic  phone I got the 720-504-0037…also not a real number.  so many scammers…6 different ones yesterday.
