Simplilearn — Fraud

They sold me a course by telling it beginner friendly. Than after joining one class it was not beginner friendly it was an advanced level corse. Then they also told me that they have a refund policy that gives refund if i dont like the course. So after joining one class i contacted them and they told me that refund will be only for 7days but my classes started after 11 days. So how can i know in seven days if i like the classes or not.
