Proving the server crash is by the console, there might be a thing saying "Server shut down" (something like that in the console) take print of that and replace instead of having the info of the server.
The proof is not really good, since we can't know if it is legit. For al lwe know you couldve jsut taken a pic of the printer and when the server went down made one of that. Anyway, I doubt this will be refunded since as we all know, the servers are going down alot at the moment, and you were told that it is better not to do things that could lose you alot of money.
