Anyway to dispute a false VAC ban?

[87 sentient lego men gaming]

I have been banned from CSGO for cheating from playing dark souls 3, I was banned four days ago but I can't even contact valve and get a response. Some of the details I if my ban are; I was playing dark souls 3 and I encountered a hacker so I added him and said he was bad for cheating, then he says "two days till you're banned :)" and unfriended me. Naturally I didn't believe him but low and behold I'm banned, VAC banned no less. At the time I had only logged onto CSGO to see if there were any changes, the last time I actually got in a match was about a month ago. If anyone had any details on how I can dispute or contact valve or steam about this ban, please tell me.

No, bans are non-negotiable. Read this: http://steamcommunity.com/discussions/forum/9/882959527688934488/

There is no such thing as "false" ban so there is also no way to dispute them.

Nice story but thats not how VAC is working, also why the heck do you add a hacker and talk with him?

Anyway Valve will never explain why somebody was VACed and also its useless to contact the Support.
