I think it's a phishing scam, don't go to site and log in. I found a few links which explain it. I will list them below.
Apple GSX Access Privileges pretending to come from gsx_notifications@apple. is one of the latest phish attempts to steal your Apple account
This one only wants your Apple log in details Many of them are also designed to specifically steal your credit card and bank details, your email, facebook and other social network log in details as well.
The original email looks like this It will NEVER be a genuine email from Apple or any other company so don’t ever click the link in the email. If you do it will lead you to a website that looks at first glance like the genuine Apple website but you can clearly see in the address bar, that it is fake. Some versions of this phish will ask you fill in the html ( webpage) form that comes attached to the email.
Dear GSX User,
Your access privileges on the Apple Global Service Exchange (GSX) system were revoked by GSX_Rejections@group.apple on 19-Feb-2015
Reason for Revoking access
I took out the .com so no one would click on the phoney link by mistake or just cat curiosity.
I hoped this helped, Also I use mywot which tells me if a site is legit most of the time.
