A lot of sellers on Fiverr are selling stolen copyrighted materials like videos, logos, etc.
Fiverr knows that very well and they are partners with those thieves. If you open a ticket, they will ignore it and close it. They simply don't care. They care only how to collect money in any way. No ethics or morals. Fiverr are a bunch of thieves and most of their sellers.

Very low-quality, unstructured and overpriced content. Most cases have very basic unprofessional answers or no answer at all. I've used my premium account a couple hours.
They collected free materials and numerical test samples from around the web, changed the title to disguise it as cases used by McKinsey, BCG, etc, and charge you overpriced membership for it.
They will refuse to refund your money in all possible way.
