Keeps calling my house then no one there???

Phoned at 2:45 A.M.  When I phoned that number back, Telus told me that number was not in service.

calls from this number are a nuisance call.  When you call back Telus says it is not in service.

this number keeps calling but this morning someone actually said "hello this is" and then hung up...any other experiences?

they have called numerous times over last few weeks.  always a different person talking as soom as they start their spiel I hang up.  giong to try to block their number.
