Called and did not leave a message, now have blocked this number.

Robot message for air duct cleaning.  I pressed 1 and asked how did you get my number.  Lady said white pages.  I told her they do not list mobile numbers she said Yes they do.  I asked her what company for white pages did they use, she said what I can't hear you and connection was lost.

Unknown call to my number. is it me or are these scams increasing.
