Two Game Center Accounts on One Apple ID

Hello,

From the looks of things I'm the only one experiencing this issue and it's really starting to bug me out unfortunately. There's an APP that I use on my spare time. When I first installed the app it was registered under my Apple ID and Nickname "San Huevon". For some reason I got bored of it and eventually a few days ago I got hooked on the urge again. Only this time when I went back in it asked me to load my profile or create a new one, so I created a new Nickname "SanHuevon" technically speaking but still registered and logged in through my original Apple ID. After a few days of playing I loaded the app and accidentally clicked on "load profile" it loaded my old profile and now I've lost all in-app purchases that I had purchased in my second profile. I've tried changing my Nickname back to the second one which was "SanHuevon" without the space and it says it's already taken. I've been unsuccessful at this, whenever I contact Apple Support it's as if I'm talking to another country?

If anyone has gone through this and can shed some light I would greatly appreciate it, although I'm sure I'm just out of luck on this one.

Thank you all in advance for taking the time to read this.
