Geolocation: IPv4 Subnet blocked by HULU, and others

I am a local WISP. And my customers have trouble reaching Hulu, Disney now, and previously netflix and amazon prime(both resolved). I have emailed, mailed, and called both HULU and Disney now to get my 196.53.96.0/22 subnet unblacklisted as a VPN provider(no longer so) from their services. They have replied saying it takes 3-5 days to resolve the issue, that was several weeks ago. Can i get contact from those two services that can help my customers reach their services, thank you. Thank you for the help. -Michael
