Called me on a Monday at 4:45pm. I missed the call and the voicemail left was the tail end of a recording saying, "...further details please press 1 now. Press 2 to be placed on the do-not-call list." When I called back, a guy answered and said he had no idea what I was talking about and it was a personal cell phone, not a business. Maybe they are calling through someone's number somehow? I never got called again by the number.
