Similar experience, claimed to be from Amazon asking for my 15 yr old daughter by name. I cannot put the words I used here, but they were not at all polite. I hope the sscamming scunts fall down a deep hole.

He said he was from Amazon regarding my account with my own domain email. Apparently own domain emails have to be switched to an Amazon one. Or I think this is what he said, the english was very poor.

They say they are Amazon. But email is from Amazonses.com so may not be Amazon as this is an open email system. Suspect SCAM!
