Payment failed when trying to pay for a Xbox 360 exchange

As the message itself says, you will have to change the form of payment, if by chance you have already exchanged and still failed, so I suggest you make the purchase through an Xbox 360, the chances of error are lower, of course, if it can be done for
you.

When the memory units fail in those Xbox 360 consoles, you can't delete or install anything and you'll often get prompted to install a system update which won't install either.

If you can try and exchange the 360 with gamestop that would be best and get a 360 without a memory unit. The systems without a memory unit will require an internal hard drive.

The 360-branded SanDisk drive is failing the performance tests?

Take it back and exchange it. The 360-branded SanDisk is not supposed to do that.

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello MrYoavon, by your description you are trying to make the exchange for the Xbox website, but if when trying to exchange your gamertag, the system does not provide you with the option to pay with the account balance is because it only accepts credit or debit cards for the exchange of the Gamertag.

Sorry to hear it. Are you trying to pay with a valid payment option or currency on your account? You can only use currency to buy 360 games if you're on an Xbox 360.
