ClarityCheck Unauthorized Charge - Refund Request

I am writing regarding unauthorized charges made by Claritycheck through my Apple Pay account in Spain. Last week I was charged a small amount (around 0,50–1 €) and today, 28 February, I was charged 30 € again, only about an hour ago. In total, Claritycheck has taken 31 € from me. I only intended to make a single one‑time payment of 50 € previously and I did not subscribe to any ongoing service or authorize recurring payments. I was not properly informed that I would be charged again, and I feel misled by the way this payment was taken. For me this looks like an unauthorized charge and a deceptive practice. I tried to get a response from Claritycheck, but I have received no reply so far. I do not accept these unexpected charges and I want this situation corrected. I request a full refund of the total 31 € taken by Claritycheck without my clear consent and the immediate cancellation of any hidden or unwanted subscription or recurring payment linked to my Apple Pay, so that no further amounts are charged in the future.
