That is exactly what I did 
The response I got:
Hi there,
Thank you for your information about this incident. Unfortunately after our review we will be unable to remove the models in question. With time and dedication could be built to replicate your models, and this is not against the Rules of Terms of Service.
While you do retain a copyright in your UGC, please read the entire section of the Terms of Service found under Section 6B subsection ii note b. Please note that other users on Roblox are allowed to make models that are similar to yours.
Sincerely,
