CamScanner Subscription Charges $54 Without Consent on Google Play

I discovered today that 54 dollars were taken from my account for a CamScanner subscription through Google Play, even though I do not remember ever purchasing or knowingly approving this subscription. I only noticed it after seeing the charge linked to my Google Play account. I tried to cancel it myself, but could not figure out how to do it and was not able to stop or reverse the payment. I live in Texas, and I am using CamScanner via my Google Play account. I request that this 54‑dollar payment be cancelled and fully refunded to my account, and that any active CamScanner subscription linked to my Google Play account be terminated so that I am not charged again in the future.
