Cannot access my US and Canada stores which has blocked my primary UK stores

I have a UK store and was using this fine for 9 months. Then I added the US and Canada stores and have had endless problems. The key one now is that due to me not having access to verify my US and Canada stores they have deactivated my stores and I do not have access to them to rectify this. As a knock on effect this has resulted in my UK stores being deactivated as well. I have been trying on and off to sort this out for 6 months and it just seems like there is no interest in the US platform to help a seller based in South Africa. There is no direct contact number to speak to someone and the messaging sent via the UK helpdesk done reach anyone who can help me. All I would like to do is sort out the US and Canada stores verification, and start selling again to survive...its been 6 months.

I cannot access US and Canada stores via my UK seller central platform as they do not appear on my list of stores

I am also now unable to log a new case on the UK platform -

The contact numbers for support do not offer one for South Africa

Calling US customer support is just a circular nightmare
