un authorized payments

When purchasing via phone number you get a text sending you a code which you must enter on xbox to confirm that the number entered is yours. So this means whoever had made the purchase had either access to your sons phone or had been given the code by
someone who did. Also if your son has his own separate account check the order history on his profile as someone may have used his account to purchase items and you will be able to see what exact items was purchased. Also as I do not work I cannot help with
this sort of problem I have tried to give information of which might be able to help you figure out if you know whos been using your sons phone or xbox account.I would recommend contacting Microsoft again as this would be classed as someone doing fraud with
your details.I also suggest removing your details of Microsoft accounts until the problem has been solved. https://support.microsoft.com/en-us/contactus/

Merci pour votre réponse rapide.

Précision concernant le paiement par CB, quand la transaction est effectuée, une autorisation est demandé la banque et ensuite microsoft autorise le paiement sauf que pour mon problème, ma banque autorise le paiement et qu'il est refusé ensuite par Microsoft
(sachant que mon compte est approvisionné et que je n'ai jamais eu de refus de paiement). d'ou ma question, y a t'il un nombre limite de transaction de paiement par Microsoft ?

Sur une journée, j'ai crédité 2 cartes de 50€ ce qui est très loin des 1000 USD par jour

[Translation - Thank you for your quick reply.

Clarification regarding payment by credit card, when the transaction is made, an authorization is requested from the bank and then microsoft authorizes the payment except that for my problem, my bank authorizes the payment and that it is then refused
by Microsoft (knowing that my account is funded and that I have never had a refusal to pay). hence my question, is there a limit number of payment transaction by Microsoft?

On one day, I credited 2 cards of 50 € which is very far from 1000 USD per day]

Are you trying to purchase the game from your console or from xbox live online? I found that if I try to purchase from my xbox live profile on line I have that problem, but if I go through my xbox console to purchase things I don't. Also you might want
to check to make sure the 3 digit code on the back of your card has been entered, because that can also cause your card to be declined/ give you an error reading.
