Falsely banned for cheating

I was just banned from the game after having bought it just hours ago. I got an email saying i was flagged for cheating but it didn't go into any detail at all or give me a specific example of cheating on my end. I had to leave a rivals game because the game wasn't loading after 2 minutes of waiting in a black screen. I was playing with a friend who had to do the same and he wasn't banned. Is there any hope of this being resolved quickly because i was hoping to play over the weekend. I've emailed and i believe i have disputed the ban though i'm not sure because the process isn't clear at all.
