How can I cancel my Dynalist account?

I have already made a Dynalist account for one year, thinking it would let me try it a bit more, before the payment. I realized late that the pay was made. Honestly I like Dynalist but I don’t really need it. I can’t find any mail to ask for, so if someone can help me to cancel my account and get my money back, I’ll apreciate a lot!

I have refunded your payment.

Thank you very much, Shida! So kind of you.
