I just found that my account is stolen to purchase XGP subscriptipn and 7 Assassin's Creed Unity gifts, and found that I have no way to contact Microsoft because somehow rhe mail can't be delivered:
550 5.4.1 Recipient address rejected: Access denied. [CD1PEPF000006AE.namprd00.prod.outlook.com 2023-08-30T05:27:59.113Z 08DBA8FDD7198C46]
I wonder what else can I do? The fact that I'm undergoing a recalling military training and I don't havey mobile with me most of the time to resolve these security issue makes me a bit more anxious.
I will be very surprised if it's not something wrong on my end that the billing support is not accessible for such a big corp.
