Said they were from Direct Buy, when I asked not to take us off of call list the woman became very rude.

They wont stop calling me

Received call.  No voicemail left.  Thanks Patty Dunn for the detail.  If it was Direct Buy, I know I gave them my number a month ago.  Not happy with these calls.

they keep calling after I ask them not to

I received lots of calls from this number but no voicemail was left.  Then I answered the phone they asked for someone else, and said they were "returning a call".  I said wrong number.  Two hours later they called back with the same story.  Sounds fishy to me, but maybe they really did just have a wrong number.
