DMCA Counter Notice

Hello,
my game got previously banned because someone asked for my game file or else he would ban my game, then he did it by DMCA my own game logo image whitch after I sent email to Roblox Copyright Agent with all the information date and step by step creation they responded that my own logo image was owned by someone named WhyNotLeuasde an alt account created 5 days ago.

After that I resent an email showing more proof but they responded the same with one new thing “submit a counter-notice”

I would like to know how could I get my game back or submit a counter-notice
(I can provide screenshot if it can helps)
