no message and you cant call back

This was yesterday on my cell and heavy accent difficult to understand - offering $100.00 gift card from Walmart for the shipping and handling fee of $3.95. They said they needed my credit card number to process a free Wall Mart 100.00gift card. Very heavy foreign accent, India maybe, hard to understand. Foreign accent stating he was with USA benefits. He stated I qualified for a $100 Gift Card since I used my VISA card somewhere. He had my name, address and phone#. Today he said he needed my Visa info to process a $4.95 fee to activate the card. I just need the expiration date. So I gave him expiration date, and he proceeded to try to get my credit card info saying it was okay since he wouldn't ask for my PIN number.

A robotic voice calling to confirm my order, and I haven't placed any orders with anyone. A callback during business hours gave me no opportunity to connect with a live person. I'm monitoring my bank accounts closely.

he called me every half hour for the last 5 hours left no message. i finally picked up the phone call and ask him to leave a message, which he said htat wasn't nessecary that would call back. then he called me back after fifteen min, i ask him once again to leave message refused to but gave me his name and said he would call back.
