If you've spotted a £47.97 charge or similar on your bank statement or credit card bill with the words "Prime Member Fee" next to it and don't know where it's from, then it's likely you've inadvertently signed up for online retailer's paid service such as Amazon's One Month free trial of Amazon Prime.
Once the month's up the annual fee is £47.98 so that sum will have been
taken from your account. To ensure you don't pay a penny you need to
cancel the service.
Provided you or any registered guests on the membership haven't made any
eligible purchases then you can cancel at any time once the trial's
finished and the full amount will be refunded.
To cancel, the quickest and easiest way is to go to the "Prime Settings"
section of your Amazon account page and click the "Cancel membership"
button. If you'd prefer to speak to someone in person to do it you can
call Amazon's freephone customer service number on 0800 496 1081.
The refund should be in your account within two days.
If you're still within the trial period and want to cancel just click
the "do not upgrade" button in your account's Prime Settings.
