What additional documentation can I provide for my freelance visa application in Thailand?

Hey there,

I uploaded soooo much when I was applying (freelancer), including invoices I sent to my customers every month of this year, bank accounts, recommendation letter from my current project I'm in since January with a stamp and sign and so on and so much more.

Today I got this.

Anyone got an idea, what I can send them?

Because my current company is in vacation, so no chance to get a business registration from them any time soon.

I'd be happy if anybody has an idea.

If it helps, the company is German and I'm German and I'm working for them on a freelancer base. So I send them invoices every month.

The "Gewerbeschein" they have is from the 80s and they don't have Handelsregisterauszug since it's a "Einzelunternehmer"
