Chinese scammers

So there is this number that keeps calling me it’s XXX-XXXTX and everytime the answering machine picks up it leaves a voice message in chinese, they keep calling and the number is just a bunch of x’s does anyone have any suggestions?

I have a very similar problems its about every week I get the call and the msg it leaves is in chinese. They sometime have the xxx-xxxx sometimes its a actual number. I will post the number next time I have the pleasure of hearing the robocall. Wish I knew what they were saying lol
