Unreturned products

I’m the owner of DKMY cosmetics. I had requested Planet Web Design to create a website for my business early last year. The consultant by the name of Nadine requested that the products must be collected for photoshoot. Indeed the products were collected & the website was created but the products were never returned to me till today. I have been in contact with Nadine for the products to be brought back but she keeps on telling me that she will follow up. What hurts me the most is that my business is stuck I’m not happy with how the matter is being handled.
