Devastating experience with this AI enhanced support system

Hello, 

After weeks of back and forth Im really exhausted by Ebay's organization - my case was really simple and we lost extremely long time without any resolution. I'm member since 2008 and haven't used the support in years, however I can't even find the right words to describe my experience from the whole ordeal. 

Long story short - my nationality in personal info section is wrong and I cant change it. So I contacted the support and explained the case and that I can verify my identity with ID, documents and whatever required. They said through chat that this will be handled by another team in 72 hours. Fast forward a week ahead nothing happens - I contact them again, they say that I need to create a new seller account because nationality cant be changed and this happens from time to time so it is perfectly fine to have 2 accounts. 

I created a new account and it was immediately banned.... If I try to write them from my original account they say because of GDPR they cant help. If I write them from the banned account no message goes through because AI system filters it. I tried to request a call - as soon as I picked up the call other side cut off the line. No way to contact anybody. 

My case is totally legit, Ive never caused any issues and always followed the stated rules. In the end this does not matter at all. 

If you wonder why I need my nationality changed it is because of VAT. I want to sell my items and ship them, from EU country, I'm EU citizen but due to UK status of my account I get hit with over 20% VAT surcharge which makes them unsellable... 

At this point I my last hope is if someone can tell me how to reach a real person who can actually help. That would be a huge relief.

Also if by any chance any support members read the forums case ids are 
SR# 1-505707422315 and [THREAD ID:1-6GC30OR7].
