Who called from 7272050835

I picked up thinking it was a work call, but it just beeped once and then hung up on me. Calling back only gave me a disconnected number recording.

Didn't recognize the number so I didn't pick up.

Same thing, couldn't call it back

Samething they call hang up when i answer and then it rings busy when i call back what a pajn n [***]

Some is not right with this phone number.  When the phone was answered the "mute" signal came up.  What is going on?  Don't answer this number.
