Missed call went to VM but they left no message after 5 seconds they hung up. Rang number back :- "not a valid number". Rang me a second time, I answered and they hung up. Obviously they have a sucker radar and my booming voice said there is no way this guy will buy anything off me. Ugly side of modern technology.

Keep getting calls daily I call back and says number disconnected a nuisance call! Would love to know how they received my number!?

They did not speak but hang up after couple of seconds.
