I get on average 6 private number calls a day. If I answer them, there is a 2 second delay then it disconnects. If I leave it, it rings for 20 seconds and stops.
I cannot block them because there is no number to block.
Is there anything I can do to stop this?
I have tried screaming at them, using a compressed air bullhorn. Nothing works. I suspect it is automated so those solutions are ineffectual.
