Who called from 2699033536

got a call once...no one answered when i called back

called at 8pm and when i answered no one talked. tried to call back and it just rang and rang

Same issue - received call a few minutes ago, no one spoke. When I called back, no one answered.

same thing calls  every so often, no one says anything and when you try to call back it just rings, me thinks it's some kind of spam/collection phone verifier to see if you actually have and answer your phone but that could just be paranoia  :)

I have gotten numerous calls from this number.  When I call back, it just rings and rings.
