Hello,
Just a simple Google search (only search Skillshare scam) will show you hundreds of people complaining that even if you cancel during the trial period, Skillshare will charge you and will not provide any refund. They don't even allow you to remove information about your credit card which is bizarre. I had to contact them after I cancelled my trial and had them withdraw my credit card information and delete my account after about 20 emails were sent back and forth, and eventually they did it.
After 4 days I see $120 charge on my credit card even though I don't have any account with them anymore! And they don't respond to any of my emails plus they don't have any phone number in their contact. It's also bizarre (and definitely intentional) that they don't send you confirmations when you cancel your trial period or even register with them.
