Skyline Social lies, terrible service/product and no morals to fix the issue after admitting they were wrong! Florida

I bought a marketing course from this company who completely mis-sold it to me. They did not deliver at all on what they sold, they admitted to having no idea why it didn’t work and no idea how to fix it, but still refused to refund my money. They charged me thousands of dollars for their course and cost me thousands of dollars paying for other things to make their course work, which it didn’t. I’ve tried speaking with the company directly and I provided all the reasons why a full refund is the least they should do, but they still refuse to do so.
