Yes, I've been getting these two for several weeks now. Slightly different numbers but only one or two numbers off, so it's obviously the same people. And yes, same MO- they don't leave a voicemail. I've already gotten two such calls in the past hour and a half.
Just got two calls from this number in the past hour . I let my answering machine get it both times since I didn't recognize the number, but no message was left. Pretty annoying. It looks like I'm not the only one getting these calls today.
