19 days(15 business days later) Roblox did not send any follow up on the counter DMCA neither restored the content, even though the DMCA claim was invalid and not legal.
When I send a email they do not reply. Is this normal?
Roblox isn’t like it used to be anymore. They never do things when they say they will. This is pretty normal. Your game will probably be back up in 1–2 days, maybe even a week later.
