Then dont allow you to login or use the support services later on because the email contains a +. So I get their emails, including eventually one about the cancellation, but still havent been able to login or use the support for my account. And if I post on the forums I just get the shitty advice that I need to login to support services or request a password reset because neither of those allow + in the email either. I also received what looks like a ban for using curse words in my support request at one point, and yes I did use <name>+shittyuplay so well thats true, but if thats the damned problem dont let me register it in the first place.
I dont care anymore since the game I registered was just some shitty thing that came with a graphics card, but I am astounded at how incompetent they can be while still trying to become more popular than steam. Steam only needed to provide better service than pirates, but Uplay needed better than steam, so well they are doomed and good riddance.
