I've had this same issue and they still haven't responded... any luck?

Sorry to hear those password resets aren't arriving! First, try requesting them from a different browser and checking your junk/spam folder. Also, make sure your email is not blocking or filtering emails from noreply@mojang.com. ^NS

Everything should be correct, my username on a skin website doesn't show any results and I believe my email has been changed. It's been more than 48 hours since I emailed and still no response.
