They are scammers. Willing to sell any service or item (which sounds good to you).
They only Want your personal info. So, when you do give them a bank account or credit card# ?? DON'T BE SUPRIZED WHEN YOUR money is missing. And, the item never arrives.
It's all a part of the scam from 2nd & 3rd world countries. America is a laughing stalk to them. Too many gullible people willing to give their money away. We all should see the website NumbersUSA.org
God Bless America
