Sounds like you got a 4670 then. Take it back if you want to make sure you didn't "steal" it. I personally wouldn't worry about it but....
no i didn't steel it but box seal is open at time of purchasing it
I meant steal as in you paid for a 4650, but got a 4670. There are many possible things that could have been going on, not sure I'd worry about it. Your Indian however so you might need to take Karma into account.
