Finding a Seller

In August, I bought a notebook on Amazon. I want to buy more of the same but the seller I guess isn’t active. I can find tons of inactive listings for other notebooks but nowhere can I find a way to contact seller. Shika Sugiki is listed as the author on Google books (or whatever) and Greenways Technologies is the Amazon seller. Wu Bills Notebook is the product. Can anyone help with contacting this seller? Ty.
