Amazon PSN balance Enter default address?

I recently wanted to buy a 50 euro PSN credit card from Amazon, so I entered a gift code and wanted to buy it. For some reason, Amazon wanted my "default address". Then I entered my correct address, but still could not buy it and got the same message. Does one know what I did wrong? If not then I have 50 euro on my Amazon account, which I can't use.

What message came the

That's because: "There was a problem with some items in your order (see below for more information):
Please set the default address https://www.amazon.de/.../addresses to purchase this product. It's currently removed from your cart. All package discounts for this product can't be considered at the time of purchase. "

Funny I do not know I have also brought me an object that is from 18 (under 18) and something did not come up with me

I had to verify my persona and now that. I entered everything correctly and tried it several times, but it still does not work.

I simply entered an account and selected the coupon number and was able to deposit it

That's exactly how I did it, but it just does not work.

It worked now I had to set my address on the PC as a "default address" then it went.
