unknown call no mesaage

Got a phone call from this number but since I didn't recognize the area code I didn't answer. No message left.

just got a call from this number......know NO ONE in 302..........did not answer..........no message left

These jokers called me from 302 394 9674 and didn't leave a message, so I called back.  It's WCA, some type of subscription service, and they said that I subscribed to this calling service about a year ago.  This is total BS.  If you answer the phone prompts, you can supposedly cancel, but before you can do this they give a laundry list of what a great deal it is to be a subscriber because they give $100 a day to people that they call, and IPODs etc blah blah blah and why would I want not to be a moron subscriber? So I cancelled of course.  I'll repost if this cancellation doesnt work
