Help/Support Real racing 3 banned / Keychain

[ThekingB 0 iPad Air 9.3.3]

Hello everyone and happy new year !

so I recently downloaded real racing 3 ( I didn't play the game for so long, and back in the days i used the lockalIApstore tweak I think ) I added my Facebook account to the game yesterday and I got banned  the message says something like " 

you can not participate in this race as long as you are banned .. " 

there's no code number so I don't know for how long I'll be banned, the thing is that i want to play with this Facebook account because all my freinds are added in it and it's the only way to see their scores etc, I really need to play with it and I don't mind loosing all my progress and starting again from zero, so does anyone knows a way ?   I tried to delete the keychain like with gameloft games but I didn't find the real racing one so if anyone got an idea.. I'll really appreciate it ? 

Ps: i allready logged out from Facebook/Game Center And The game Will play normally, but like I said I need this Facebook account and as soon as I open it in real racing 3 I get banned, I also tried deleting the game from Facebook but it didn't add much and I started my progress from zero bit always the same problem with Facebook account   

waiting fot responses, thanks a lot  !

Don't play with the keychains, otherwise you'll screw up the game even more.

other than that, I don't think you can unban yourself yet unless you contact customer support.
