Кто звонил с номера 9780000000

this 1 978 000 0000 has been calling for a couple of weeks. Today 5 times. How do you get it to stop or find out who it is.

We have been receiving calls from this number the past week.  Today, Sunday, we have already been called 6 times.  They never speak and usually hang up after a few minutes. Today no one hung up - I could hear people talking in the background like they were on another line.

Same thing as everyone else ~ 13 calls in 24 hrs.  No one there.  Who can I/We call to get them to stop!

called here in NH no voice, no message

They keep calling and hanging up no messages, but it is annoying they called at least 10 times yesterday
