I noticed that you have charged my account without my permission on (päivämäärä).
I have only purchased a (tuotteen nimi jos tilasit edullisen tuotteen mutta et muuta) from you and paid XX€ (lisää summa) for it, nothing else.
I have only participated in your competition/inquiry (jos osallistuit vain kilpailuun tai kyselyyn) and have not ordered anything.
Kindly cancel the subscription immediately and confirm that you will not charge me more.
I also ask you to refund the XX€ that was charged from my account.
I would appreciate your prompt response, but request a reply to be provided within 14 days of receipt of this letter.
