These losers called me on a Sunday afternoon. I answered, but didn't say anything; I wanted to see if they would say something. If it were important, they would have. Never did. In fact, hung up quickly. Blocked.
Got call from +1 210-714-7681. Didn't answer. No message left. Found many such calls reported on this and other sites. Likely a telemarketer (scam). Added number to auto-reject list. Done.
