Some terrorist called claiming that I won a Walmart gift card. Then said I had to pay for an activation and mailing fee. I told him to pound sand and he kept begging for me to stay on the line and listen to him.

Same for me too. I got a call from them about this $100 walmart  gift card and asked me to pay them $4 for it.
I am from Bangladesh and settled in US. But they said 'bloody Indians" when I refused to pay them anything.
This could very well happen to a Bangladeshi or any other natinoanlity person.
Where can we report such cases to screw these [***]?

I keep receiving multiple calls from this number and I never answer and they never leave a message. They have called so much back to back that I decided to Google the area code and I found this forum. I'm happy I did now I see it's not necessary to worry about it.

Tried saying I one a free $100 gift card. On the third time they called I told them I wanted my number removed from their calling list and that if they called again I was going to report it to the police. We'll see if that keeps them from calling or not. I also placed the number on my Galaxy S3's Reject List. I suggest you do the same if you have that ability on your phone.

They have called me 7 times within the past hour. It is obviously a big scam because no professional business would call that many times just to beg for money. If you do answer, I would threaten them that you are going to inform the police.
