Hi there, Beltron.

I can help you direct to our phone support who can help you cancel your subscription. 

Keen in mind that the security of your account is our top priority thus, one of our agents will need to take a look into your account to verify the charge and cancel the subscription for you.

Here's how:

1. Go to this link: https://help.quickbooks.intuit.com/en_US/contact.
2. Select QuickBooks Online.
3. Click on Search for something else and enter your concerns in the Tell us more about your questions.
4. Tap Search.
5. Click on Start a message.

Please take note of our business hours to ensure we can attend to your needs.

Once the account is canceled, you'll still have read-only access to the account for a year after the cancellation date. 

I'm only a post or comment away if you have any other questions. Have a great day ahead.
