Got a disconnect when I picked up phone

I missed the call but called back and identified itself as Lisa from Reward Redemption. I could press 1 to receive my "reward" for visiting one of their websites in the past few months. After doing research, Reward Redemption uses many numbers and all use "Lisa". THIS IS A SCAM!

This number called my cellphone 3 times in a row with dead air calls.  I will be reporting this number to the DNC, FCC and FTC since I am on the Do Not Call list.

Received call from this number.  Caller hung up after 2 rings
I do not answer call from numbers I do not recoghize

Same thing w/me. So Annoying and I will make report as well.
