I'm sorry for what you've been through. We do have a very bad supply chain issue this year so we couldn't make a lot of H9 earlier. Now it's getting better and we are shipping H9's to Europe.
Based on your diagnosis, it's likely this is a bad unit. If it's a new unit under warranty, we can repair this unit but you need to send it it and it will take a while. So the ideal solution would be exchanging or returning this unit to the seller.
