Flying ball boomerang patent infringement issue

I would appreciate if someone is able to help me. I have been trying to sell the flying orb ball boomerang drone which i am sure you may heard about and hopefully someone is selling it.

How do you possibly manage to get the right selling authorization etc as it seems like all versions of it have been design patented in uk from random chineses which reported and i am being unable to sell the stock. I was not aware that this product had a design patent in Uk. I tried contacting the claimant but they never responded.

On amazon there are over 20 accounts who are selling that drone somehow, i don’t understand how they manage to sell it if it is the same product and i cannot.

This issue has caused me so much stress as it looks like there’s no way around it even though i did lot of research.
