Who called from 3134500714

anyone know  who this is

313-450-0714
This number called us, claiming tp be ADT alarm systems wanting to know if we had an alarm!
Hung up promptly on us with no call back answering their phone number when began to question them.  Don't know if it's crooks trying to find out which houses to break in to or what.

This number called us and as soon as I answered they hung up.

Don't know, I never answer phone calls from numbers I don't know.  Caller ID shows "BLOCKED" with the number also shown!

got the same call today. too bad i'm protected in more ways than one.SCAMing SOBs
