Product Category Mismatch on Seller and Vendor Central

We are a manufacturer who recently started selling our products on Amazon through seller central as well as through a Vendor
My major selling product is unable to get added on Amazon because the category is mismatched, while the product is listed under PCA on seller central, it shows up as GL_Furniture in vendor central according to the support team but other competitors are already selling that product through the same Vendor
I am sorry if I am not able to explain it clearly but that is all the information I have been able to gather from different sources, I have contacted the category manager through unofficial means but he/she has been unable/unwilling to help
My question is how can I solve this issue and whom can I contact higher up
I am selling in the Indian Marketplace
