I have no idea who the 404-902-5683 belongs to but I am sick and tired of getting phone calls and then when you try to call the number back, you get the message this number is not a working number.  I  want these calls to stop.

They call and will not say anything.

phone rings l pick up and say hello a couple of times then l hear automated system say good bye ,when you call the number back it gives a recording the number you have dialed is not in service .l wanna know how to block this number

Called me with information they had on me about diabetic supplies and ask for my doctor etc.,  but when I called the number back it had been disconnected?  Sure hope I have not been scammed, but looks like it.

404 902 5683 Calls and says nothing and when you call it back it is not a working number.  Is this some type of survience or security system setup?
