If you sign up for a free trial and add your card on any platform, please cancel before you're charged for a full subscription to avoid billing.
However, if you have been charged or encountered unwanted card transactions, please get in touch with the merchant website and contact their support team, as we can’t cancel or issue a refund because we do not have access to third-party websites.
Only the merchant can, depending on their policies. You can see the name of the merchant involved attached to a transaction.
You can check out various merchant policies on their website: Apple, Amazon-prime, Netflix, and Google.
