I purchased Magnoliyan Video Chat From Code Canyon

Magnoliyan Video Is supposed to be a video chat script and I have Posted Jobs on Fiverr, Freelancer, and Upwork. I have even Had my hosting company Try to Install this script and nothing has worked. I bought the script because of the demo’s and the documentation that sell it to people, but everyone I spoke to who are experienced web developers have given my money back and refused this project. If these people can give the money back why can’t code canyon???
