I think the correct statement would be, "one other person is having the same issue as me and also believes that he possibly received the wrong tang." That would be more accurate. Sounds like he also received his yesterday and hasn't allowed time for fish to acclimate. And as far as the pictures go, neither picture is your so we cannot identify whether you got an incorrect order.
I'm not stating that you didn't receive the wrong order. All I am saying is that you should communicate with Mike first before you go on here and start bashing on the vendor. For all you know, tomorrow, next week, or next month, your fish will start showing yellow around the eye and then you will (hopefully) feel like a fool for bashing Dr. Reef. Another scenario, you send him pictures. He apologizes for sending you the wrong order and makes it right by sending the correct fish. Who knows.
I just think that you're jumping to conclusions and being emotional for no reason. Find you answer first and then when you do in fact have the correct information, come on here and share it with us, regardless if its good or bad.
