Amazon brand registry application rejected. What now?

I wasn’t expecting this to happen today, but the brand registry application I took an hour to fill out was rejected a quick 30 minutes later. Apparently something with my registration number and my tax ID number was incorrect? I don’t even know, the information for rejection was very vague. Naturally, I’m a little nervous about my timeline now . It’ll take at least three months before I can submit another application so I’m moving forward in the only way I can. My product is already in production and I assume we’ll be able to sell before the three month mark. Can I still use my brand name in my title on my product listing if I don’t have brand registration yet? I’ll just have to launch without a storefront. Will brand-name approval be my next best option? Any advice will help.
