They called several times when I picked up a man's voice says "Sorry wrong number" I think is a way to get leads as far as what time the person picked up the phone and they record it for tale marketing purposes, they still believe that it works? Also it may be associated with this number 727-431-3388
FCS is what shows up on Caller Id, Even people like myself that are in the NO Call list are still getting these calls, they should be ashamed.
