Who called from 9132706776

I received a call from this number today. My call ID read "Support" I did not answer and no message was left.

Called but left no message. No idea who it is or what they want

Same experience as the above comments. No message left. Number will be blocked.

Persistent caller. Does not identify who it is.  I blocked this number but it keeps on calling me everyday.

Unknown number so I didn't answer.  One unintelligible word of a recorded message was left.  Number is added to the growing list of blocked numbers.
