Greetings!
This is Tin, I'll do my best to help. Have you tried to check if your subscription is active from the subscription page already? If not, please sign in to https://account.microsoft.com/services, please check if it's activated from there. If not, please try your other email account that you might use to purchase or pay your subscription. But in case you only have one account and you already paid for it, it will be best to reach MS Accounts & Billing to check on this.
Kindly open this link: https://support.microsoft.com/contactus/
Please sign in your account with the subscription, then click Microsoft 365 then choose Get Home Support. After that, please type Chat with an agent then hit enter. Scroll down and choose Contact Support, then please select MS 365 and Office then under Category, choose Billing and Account Profile question then hit next. You will see the chat option there.
Once you're connected to the Live Agent, please let them know about your issue so they could check your account and address your concern.
Thank you,
Tin L
