Hi. My name is***** your computer, have you updated your payment method after logging in to
your Amazon account?
Once logged in to Amazon, open the menu under your user name and select
Manage your content and devices
enter your password ***** if requested
on the new page click Settings
under Digital Payment Settings
click Edit Payment Method
under Add a Payment Method
click Add a Card and enter the details.
You can then make the new card the default payment method
and purchase books without any further issue.
I can connect to you remotely and perform these steps for you
and have made an offer to do so.
Please let me know if any issues.
