I'm trying to subscribe using the net banking method and by bank shows it has confirmed the e-Nach service but Quickbooks repeatedly asks me to subscribe. HELP !!

Let me route you to the right support, @abhayswamy.

Since the bank has already confirmed the e-Nach service and you still get a prompt message to subscribe, I'd suggest contacting our Customer Support Team. A specialist can securely look up your account and assist you in subscribing to it. 

Here's how to reach them:

1. Sign in to your QuickBooks Online company.
2. Go to the Help icon.
3. From the Help window, click the Contact Us button located at the bottom.
4. Enter your question.
5. Click Let's talk.
6. Select Start a chat.

Also, you can easily update your credit card info, upgrade your subscription, or make other changes to your account through the Billing & Subscription tab. To learn more about it, kindly refer to this article: Update your billing and subscription information.

In case you need to learn some tips and best practices in managing your account effectively, visit our Help Articles page for your reference. We have articles there that you can read for your future guidance.
