Shadow banned on Facebook Marketplace?

I'm not sure if this is the right forum to post this, but I'm hoping to get some feedback from people who have used Facebook Marketplace before.

Basically, I think I've been drastically de-ranked because of a product that was incorrectly flagged for violating Facebook's policies. The product I listed was a toy gun for children, but the listing included words and phrases that made the algorithms think I had listed an actual weapon.

Initially, I made an appeal of the decision but later just chose to delete the product. However, the case still appears active and pending in my Support Inbox. It has a case number and still says "Open". No response from Facebook even though the product has been deleted. I've followed up with a couple additional messages explaining the situation. I even attached an image of the product I had listed that clearly shows a lime green plastic toy that looks nothing like a real weapon.

In the meantime, my other listings have been getting virtually zero traffic. Across 15 product listings, I'll be lucky to get 3-4 views in a day.

Is there any way to restore my account to it's proper functioning? I don't know of any other way to contact Facebook.

What would you do in this situation?

Thanks.
