Shaw Academy complaint: Shawacademy took my money

I joined their free trail in October and by an accident I clicked on something on their website (similar thing happened to many other people so I guess it’s not so much an accident but whatever) so around 1 000 CZK went from my account for some toolkit I didn’t want. I wrote them wanting a refund and they told me it is not possible and offered to compensate by giving me some more toolkits and opened courses or whatever. Thinking it was my fault I agreed and let it go. Then I canceled the membership after my free trial was done, because the courses were absolutely not worth any money and I just didn’t want to have anything in common with them. No money went away from my bank account in November so it si clear I canceled the membership and then in December 1 200 CZK goes from my account without my permission. I have sent an email to them describing the problem, some lady offered to compensate by making my membership even longer and giving me some toolkits or what which I absolutely do not want. I simply want my money back. I wrote around 5 more emails that were left without a response…
