Called my DNC registered cell on 1/2715 @ 8:33 am. I missed the call. No message was left. Call shows Vancouver, WA. I don't answer callers not in my contacts. Apparently this call was to cell numbers from Heather, the robo sister of Carmen and Rachel who call my home daily. I'll play games with Card Services on my landline but never on my cell. If youre pleasant and talk about other nonsense mixed in with what they want to hear, you can waste 5 to 15 minutes of their time. Never give any valid info. Ask about their kids or the weather or what state there calling from and how you've enjoyed your time in that state. You can also act befuddled. They will stay with you if there's any chance of a sale. This number is now permanently blocked.
