Who called from 4058656696

They call & call & call, but never leave a message.  I tried calling them to see what was up.  Nobody answered after several rings & no way to leave a message or identify who is calling.

I received a call from this number on my mobile phone.  I answered and identified myself...it was dead quiet for about 5 seconds, then a hangup.

Same thing as above.  I get calls from this # & they don't leave a message.  When you call it, it just rings.  Weird.  FYI... It can't be a collections company of any kind because we don't have debt problems.

Shows up as Unknown on my cellphone...never left a message.

Call from this number telling me my MasterCard had been stopped and I needed to press 1 to speak with their "Security Dept".  Ummm, NO!
