spoof item numbers! 5814816491/250026510836

I received three spoof emails regarding these two item numbers. One just asks for information (however, they were sent from two different emails) the other one said he sent payment and would report me to okay if I did not send the item! We did not sell him anything!! I have sent reports into spoof @okay, and all they do is send a generic response. Should I worry about these? I never click into the item number via my email, only through the official okay website. If anyone has any advise, I would appreciate it.
