I don't have paid agreements in App Store Connect Business

I registered in this summer, uploaded 2 apps. But recently I decided to add iAP to my apps, everything is ready, in Xcode sandbox everything works fine, but when I uploaded new version to TestFlight to test, when I tap on the subscription it says something like "Product not found". (I have added subscriptions to the app, and added them to the version before submitting, also, this version is in status "awaiting developer release" so I can tap a button and this new version with iAPs will be on App Store. But im unsure what to do, because exactly this verified by Apple's version is not working in TestFlight.) In Business section of my Apple Developer Account in Agreements I only have agreement of free apps, but not about the paid apps. 
When I registered I used my (R)(us)sian passport, I think this is the reason that I simply don't even have the agreement of paid apps to accept it. 
I have multiple passports, and multiple EU debit cards. I emailed apple to change the location of my account (to another EU country), but they ghosted me. They sent me emails to upload documents about 4 or 5 times, every time I uploaded my another passport, got an auto email "thank you, we will write you in 2-3 days", but either they did not write me, or they said that the document is not in English (it isn't). 
What do I do?

Also, to my situation, someone of my family has a company in (R)(us)sia, and I have in EU (Estonia). Maybe if nothing will work out with "Individual account", I should change to my company? And what is better EU or (R)(us)sian? 
Im new to this community, hope to hear an answer, or just an advice. Thank you!
