This absolutely was not worth it to try and use to port forward for my xbox. After going through 3 weeks of back and forth with them, it still didn't work and even though if they say you get your money back if you're not happy; you don't. Don't bother!
Hey Ben, I'm sorry that you weren't able to get a port forwarded to your Xbox One. We are really good at making it work, so if Tedie or Allen had problems then most likely you just have a challenging network to work with. Getting Nat Type Open is one of the things that we are great at, so I expect it to work.
Any way, if you're not happy then just send me an email and I'll make it right. We are not in the business of having unhappy customers.
