WeTransfer Has Been Charging Me For Months After I Canceled

I have a serious problem with my WeTransfer Pro subscription that I have been trying to resolve for months, but I am still being charged. I am in the United States and my WeTransfer Pro account is registered to the e‑mail address cant***@yahoo.com. Despite canceling multiple times, I continue to be billed 9.99 USD, sometimes even twice in the same week or on the same day. I have many screenshots of these payments taken from my bank/card statement. I have tried to cancel the subscription repeatedly, almost every week, by following the steps in the WeTransfer interface. However, the cancellation process does not work and the subscription remains active on their side, so the charges keep coming. I do not know the exact date of my first cancellation attempt, but this situation has been going on for months and I have at least ten charges after cancellation attempts. I have contacted WeTransfer support multiple times regarding this issue. Each time, they only suggest that I follow the same cancellation process, which I have already tried over and over without success. After these support interactions, the charges continue as before, and my problem has not been resolved. I request that all repeated and unauthorized charges of 9.99 USD after my cancellation attempts be fully refunded and that my WeTransfer Pro subscription linked to my e‑mail address be permanently canceled so that no further payments are taken from my account.
