Called, left no message-now blocked

Same story. Called my cell, no message, blocked.

Annoying call to my cell phone.........leaving no message.  There was no response when called back.

i get Annoying phone calls leaving no response when i called back

Called this morning, answered but no response and then a hang up.  This usual means they are checking the number and the next time they call someone will be on the line with some scam!
