Who called from 5703929956

they called my home.When I return the call # is disconected

number started calling every day on 12/27, no message and invalid number.

Probably another electricity switch or Police donation scam.

if you call the number back, a message said that the number is no longer in service; how can it be possible?

The number is spoofed.  That is, the caller has caller ID set to show a fake number instead of a real one or a business name.  It means the caller doesn't want you to know who is calling.  Which means the caller is either a bill collector or a scammer.
