My account has been blocked 5 days ago ... and no answers from RIOT

It seems like someone has tried to steal my account and RIOT has blocked it this past Friday. The messages asked me to open a ticket and I did it on Friday. It's 5 days that I'm waiting for RIOT to solve it, I have already provided the data requested (about 15 questions). How I can speed up the resolution of this issue? I'm an active player since 2014 .... Really bad experience .... Any information you can provide me would be greatly appreciated. Thanks
