VERY GOOD.
At least it's getting forwarded to someone in the right places.....Can you share your email to THEM ? Some people may write also if they have a little nudge and maybe reading your letter will help point them in the right direction.
Do you post on Millbusters ??? It's run by YT and is a great place to keep ALL correspondence like this....You never know who may see your letter and decide to write one themselves - and the more the better for this cause.
good work !! We may sound like we're spinning our wheels when we complain... but in reality, if we all did nothing - then nothing would ever change.
