Just got this one to my cell phone. Blocked and reported.
Reward Redemption SCAM
It's the "Lisa (or Julie or Andrew or Rachel) with Rewards Redemption" SCAM. You’ll be told they have a gift card for you (usually $100) for visiting one of their sponsors sites recently. Later on you’ll be asked for your credit card number to cover fees. It’s a big SCAM. Block it. If you want to have fun with them, ask them to take the processing fee out of the cards and just send you the remainder.
