This number showed up on my cell phone but there was no message left. I checked into it and found it's a telemarketer for getmyhomesvalue.com which was set up by a couple real estate agents and a loan officer. Their names are Steve Young, Rory Wilfong and Dave Conklin. Not sure of the numbers for them but I think you could leave messages for Dave at 717-687-3964 or 717-687-4269. I had the number for Rory as 717-394-3211 but I'm not sure any of these are the actual guys responsible. You might call and ask them but, if they don't answer I'd recommend leaving a message or you're just passing on the problem.
I tried to call myhomesvalue.com from the 877 number they provide on the internet but could not get through the voicemail. When it asked to put in an extension it wouldn't accept any input and the same when it told me to search by name. Generally indicative of a scam but, no evidence beyond that.
