Free MystN+ , Perm , and 30 day gun?

I didn't know where to post this so I posted it here.
anyways I think I found a way to get a free MystN+ , perm and 30 day gun.
First make a new account (Make sure you put your main account IGN as a referrer it will give your main account a MystN+ for free)
Make sure you rank your new account to a MSG+.
Then Don't go on that account for atleast 400-600 days.
Then check the email that was linked to your new account you made for an email from nexon. it will say:
"Claim Your Weapon Package and See Combat Arms Like Never Before!"
Then click on that and go to the bottom of it , it should say
"WELCOME BACK PACKAGE
It's been a while since you last played Combat Arms, so we're giving you a special bonus to make the return even sweeter. We've selected a pair of weapons based on your previous expertise with Assault Rifles, one
Permanent NX-Standard and one 30 Day NX-Rare:

All you need to do to claim your customized package is to redeem the below Coupon Code at the Combat Arms website!"

then it will give you a code like mine's with a link to redeem your code.

I don't know if this will work for you guys but it worked for me,
