This number has called my phone says nothing and hangs up then when I try to call it back it says my call can't be completed as dialed

Same here.  It has been calling for a few days.  Nothing on the other end.  No luck when I try to call back.

they called my cell today...I said hello a couple of times and they would not respond.

I have gotten phone calls all day long I get no response I'm not sure how to stop theses calls

When they call there is a just a beep and when I call back the number rings and rings and rings until the line disconnects. Plz help sorta getting annoying ive been recieving the calls for weeks.
