It happened to me as well, but i am under-aged. A man named John something told me i was qualified for a grant of $7000 (thick indian accent as well) and had all of my personal information. I confirmed everything, but later realized it was a scam and hanged up. He then called back again saying my name and with a whiny accusing voice why did you hang up? i then told him not to call anymore for i was under - aged and still lived with my parents (although they weren't so) he then started asking me for personal information such as my siblings, if i had older or younger ones, what school i went to and etc. I then asked him why and he said because he wants to meet me. He said i was a nice and polite girl. Then i hanged up. He hasn't called back but i`m scared.
I received the same call, he insisted that I had to clarify how I wanted to receive the money. He sent that they sent a letter and this was a follow up call. I told him to send me the letter again since I never received it and he said that in two days the opportunity will expire so there was no chance to resend the letter again.
I had some friends that started scamming the scammers that sent the e-mail form Nigeria. (Nigerian money drop) Maybe it is time to start scamming the Grant Scammers. Waste their time at the least get some money out of them at the best. Somehow we have to get the miserable rat B$#&erds to under stand it is not nice to mess with Americans.
