Urgent DMCA Counter Notice ignored

I have sent a DMCA counter notice, which is very important to me because I want to restore one of my repositories wrongly identified as a fork and then took down by GitHub. But more than 15 days have passed and zero communications from GitHub or the DMCA notice sender. This is not normal as GitHub says it will take 10-14 days to handle the request. I have created a support ticket but none is helping me. Please can someone from GitHub staff help me to prioritizie my request? Please prioritize this as it’s impacting me and my users.
