Started calling me last week (12-16 Sept 16). They won't say anything and I get a busy signal when I try to call back. The call says its coming from Arroyo Grande, CA.
Called my cell.
I don't answer unknown callers.
No message left.
Have had 6 calls from another Arroyo Grande number that I put on block.
Just blocked this number too.
Received a call from this number. My phone said from Arroyo Grande. No one was on the other line. I get a busy signal when I call back. I'll be blocking this number.
