Received a call, texted them to see who it was...no answer, keep calling during my work hours, so annoying!

They are claiming to be a prize giveaway service; if you answer the call, you get entered into a $100 daily drawing. They say every quarter someone will get $1K. They give away ipods etc.   How to stop future calls. Call the number, press 5 and she will say "are you sure you want to cancel?" then press 2 to complete.   Personally I don't believe them. There was an offer for a discount prescription card and perhaps that is how they found me. Is that common reason? Did you also sign up for a walgreens discount card?

Called two days in a row, I didn't answer for a # I didn't know, they didn't leave message.  Figured it was SPAM.
