Amazon and ordering not working?

I received my wages yesterday and wanted to fulfill a great wish with it. I wanted to buy the Huawei P30 Lite for 199 euro, shoes to work with for 25.99 euro and a mobile phone case for 9.99 euro. I kept entering my bank details because I didn't have a credit card and wanted to pay via direct debit, which always worked. But this time Amazon says that I have to change the payment method, I don't understand why. For information, I ordered a computer mouse for 9.99 euro last month via direct debit and have not yet paid for it. Time until November 15th, is it because of that? I really need help, maybe the smartphone will not be turned down soon… Wouldn't like to get a voucher now so that it doesn't work and I have 235 euro for nothing on my Amazon account. When the message came with the change of the payment method I canceled the article for the first time. For your information, I'm 17 and have often bought things on Amazon my girlfriend who is the same age also bought a cell phone via direct debit for 200 euro with her it worked without any problems Amazon drew the amount from her bank account and that's it.

It's because you haven't paid for the mouse yet.

But with a voucher it will definitely work.

If you have ordered something by direct debit and it has not yet been paid for, it is only for one reason that the account is not covered. Then the direct debit goes back and a corresponding entry blocks further direct debits. I would now wait a few more days to see if Amazon can run the direct debit for the mouse again, if your account is covered, the subsequent orders will certainly no longer be a problem
