Hello Temo,
Thanks for your question
It can take up to 24 hours for your subscription to get reactivated after you pay your balance.
This is documented here: https://learn.microsoft.com/en-us/azure/cost-management-billing/manage/subscription-disabled
If your account isn't reactivated within 24 hours, I will recommend you reach out to billing support for free here: https://azure.microsoft.com/en-us/support/create-ticket
