Cancel Chamspy Subscription And Refund Payment

I am writing regarding unexpected subscription charges from Chamspy that have appeared on my accounts, even though I believed I was only on a free trial that I canceled. I used Chamspy with the email address calvin***[email protected], and it was supposed to be a free trial, which I canceled, so I did not expect any further billing. Despite this, I was charged $46.53 on one of my debit card accounts and approximately $80 on another account in the United States. I did not knowingly authorize any paid subscription after the trial, and I did not receive clear information that I would be charged these amounts. I request that Chamspy immediately cancel all subscriptions linked to my email address and payment cards and provide a full refund of the $46.53 and $80 charges. I would also like written confirmation that my account has been fully canceled and that no further charges will be made.
