I have already registered and paid 2 months but now want out. How do I go about it?

Hello there,  pgetecha-live-co.

Are you referring to canceling your subscription? I can walk you through canceling your account so you won't be charged moving forward.  

You can follow these easy steps: 

1. Go to the Gear icon and click Account and settings.
2. From the left menu, click Billing and Subscription.
3. Under QuickBooks Online, select Cancel subscription.

Here's a link that will give you more info on what happens after you cancel your subscription.

Keep me posted if you're referring to something else. Take care!
