This "no results were found" number has called me more than once, so how can the number not exist? No message left on machine, not connected when I ring back so number is now blocked. Am awaiting the next " no results were found number.

rang my home line which is a silent number registered on the do not call register, Call went to answering machine. no message left. when I tired calling back I got " the number you have called is not connected please check the number before calling again"

rings hangs up all the time

As per comments above. Calls multiple times and does not leave message. Nuisance and blocked

Rang and hung up when I answered
No number exists when I call back.......

Same as above rang my home line today unknown number let it go to answering machine no message left
