Received a call on April 24, 2015, at 9:19 a.m.  They left no message.

John, they called me right after you at 10 am.  Left no message.

I have received 3 calls from this no in the past week. I searched it and it came up as a STD/HIV testing center in AZ.  I'm sure it's a scam because  there is no reason for them to call me. My be a spoofed number. I blocked the it. If it's not a scam then they have the wrong Number.

Solar energy telemarketer. Blocked number.

This number calls and does not leave a message.
