About ban

Hello, I am - https://steamcommunity.com/profiles/76561198963818996/ got a game lock in Dead by Daylight because a man (my friend) - https://steamcommunity.com/profiles/76561199814067994 played with cheats in Dead by Daylight on Family Sharing. As soon as I saw the blocking notification, I immediately deleted it from Family Sharing and wrote in support of Dead by Daylight. They told me that they would be able to remove the lock from my account - https://steamcommunity.com/profiles/76561199814067994 only if the user's account is https://steamcommunity.com/profiles/76561199814067994 , which was played with cheats will be unlocked. That user is https://steamcommunity.com/profiles/76561199814067994 wrote to support about the request to unblock my account - https://steamcommunity.com/profiles/76561198963818996/ , but he was told that in order to remove the lock from my account - https://steamcommunity.com/profiles/76561198963818996/ it is necessary that I personally write to them. I wrote to them again, and after 12 days they still haven't answered me. What should I do in this situation? I - https://steamcommunity.com/profiles/76561198963818996/ personally haven't played with cheats, and besides, it doesn't make sense to me, because I spent a lot of time in Dead by Daylight, have almost all the licensed chapters, and many donated skins.
