Someone from this number called 3 times asking for 3 different people. I assume they are confirming that the phone number called is a working number. Now blocked on my phone.
"Campbell, CA" called at 12:30 p.m. PDT and I thought it was a friend of mine, so I answered (but paused before doing so in case it was a telemarketer). No response, then a hang-up. I IMMEDIATELY received another call from a Los Angeles caller ID.
