Quest Support Contact / RMA link not working

My friend from South Korea has issues with controllers and has been writing with Support for 6 weeks now, around 14 Mails (!) back and forth. She is a streamer, but has a tough time talking in english.
Her controllers have issues with not recognizing input and stick drift.
She has been offered an advanced replacement, but the links for these didnt work.

She has received the RMA link and tried to proceed with the “Complete Request” step. However, the page redirects her to a checkout screen where it says that shipping to South Korea is not available. They sent her several links, always the same result and that they want to try again and get back to her etc.. This has been a very time consuming experience, with no result.

Now after 6 weeks (!) they say they have technical issues and can only do a normal RMA, where she would have to send them back first and then after a few weeks would receive a replacement.. This is really difficult for her, as she cant really do a break for her streams for that long, effectively she would have to buy new ones instead. While she has the resources, its a waste of money to do that and she would like to see this worked out instead.

Is there a way to get in touch with someone from support, so I could help figure this out with her. I am confused that this is such a difficult experience to get resolved with the support and we think that quest should have a way to make this possible.
