Can’t List Product – Brand Name Approval Required… but Support says it’s already registered

I’m beyond frustrated.

3 months ago I set up my Amazon Seller profile. Everything, including the Brand name was approved. I ended up having inventory issues on the backend, so we didn’t go live with selling on Amazon yet.

Just came back, I had to re-activate my Seller profile. No big deal.

I went to list my first product under the Brand Name (previously approved) and I get the error that “Brand Name Approval is required”. OK – so I went and re-applied for it per instructions.

Support came back and said that:

“As we understand that your concern is regarding ‘Add a product’ issue wherein you are facing 5665 error. As per our analysis, the brand name “XXXXX” is already registered on Amazon.”

So, good news. The Brand Name should be ready to go. NOPE.

I went back to list the first product. Exact same loop. The process says that approval is required.

I’ve been emailing Support back/forth for over a week. They keep giving me copy/paste responses saying that “there should be no spelling errors” and that my name is “already registered” so just go ahead and use the name.

Amazon Support has also NOT called me for 3 scheduled phone call appointments.

I’m at a total loss, stuck in this loop. I can’t add any products using my name, that’s apparently approved, but the system doesn’t recognize.
