How to Get a Amazon Music Unlimited Refund If You Were Already Charged
Amazon's official policy for subscription cancellations is that they stop future renewals, and they do not issue prorated or partial refunds for unused days.
If you were billed for an accidental renewal, go to Amazon's Customer Service contact page (amazon.com/contact-us), start a live chat, and explain that the renewal was unintentional. If you contact support within 24 to 48 hours of the charge and have not streamed any music since the renewal, support will usually issue a full refund as a courtesy.
Do not file a credit card chargeback. Amazon is very strict about chargebacks and will permanently lock your entire Amazon account, which revokes your access to Kindle books, Prime benefits, and AWS services.
Charged for something you forgot?
Renew Reminder warns you up to 14 days before your next renewal — so you never have to chase a refund again.
