My riot games account was hijacked. A letter came to my mail, saying that the mail of Riot games has been changed. Passwords don't fit either. I started hammering into the technical support, I create a ticket, a letter comes to the mail, here the ticket is created, you can track it using this link. The link is not working, it gives out "the page you are looking for does not exist". I wrote several times, as a result, there is no answer for more than a day. Does anyone know what to do in a similar situation?
