Who called from 9014019012

just called my cell phone.  rang twice and hung up.  no message.  seems to fit the mold of what others have said below.  I have now blocked the caller.

Same as above,  called and hung up, no message. When I called the number back it was an automated voice saying I had one a $100 rebate voucher.

No message, just a call.  Unidentified caller.

They called, cell phone rang once, then they hung up.

Called. Left no message.
