Language reports

Why doesn’t blizzard have some sort of system to provide evidence when reporting someone for language? I’ve been reported twice now, one getting me a week long ban from speaking, even though I don’t use the in game chat. I would ignore it, but if someone is targeting me for some reason, my account could get banned. Again, I DO NOT use the chat. I play with one person, and we talk on discord. I made a ticket, buy I’m not sure what they could do. Heck, I wouldn’t even mind a perma ban from speaking if it means I’ll be completely innocent from this crap.
