Cannot sign and follow up email not coming through

I've been trying to sign in on my Groupon account, but apparently I'm using the wrong password. <br> <br> I'm given the option to reset my password, but the email that the website claims to be sending isn't coming through, so I can't reset my password to access my account. I've checked all of my folders, but there is no email.<br> <br> It's incredibly frustrating, and there is no other way to contact Groupon support, so I've had to take this route.
