This # called my mobile, left no message. Has same first six digits as my mobile.
Left an automated voicemail about legal proceedings.
There was no one on line when I answered call. When I called back they said they were doing an interasteric test, and to hold the line. I think it was either scam, or a way to find legitimate numbers to spam from.
