Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Ivan,
Thanks for your reply,
I feel sorry to see this scenario and the inconvenience this has caused. Since there’s no mention of the subscription info, I am not sure what kind of subscriptions you purchased, in this case, please check and follow the advice in these articles to see if you can cancel your subscription:
Cancel your business subscription
Cancel a Microsoft 365 subscription
Meanwhile, If you're unable to cancel your subscription and need further help, you can get help from a support advocate who is professional with billing problems, the link is also in the above article.
Sincerely,
Sean | Microsoft Community Moderator
