I am not getting any support to resubscribe the account for past two days.

Hello there, @cryst-solution. Welcome to the Community.

I understand that you need to renew your subscription. I'm here to share an update on the QuickBooks Online India subscription.

Before we start, may I ask what error message you encountered when trying to pay through net banking? Any information will assist me in assessing the situation and determining the best course of action to address your concern. 

The subscription has been changed to Monthly billing when you switch the accounts to online billing. It is why annual subscriptions are no longer available. 

You can re-subscribe to your account by following the steps below:

1. Go to the Gear icon, then choose Subscriptions and billing.
2. Under Account activities, click Subscribe or Renew. 
3. Follow the prompts to renew your subscription. 

Please visit this article for further details about re-subscribing to your account: Renew my account subscription. 

If you run into any problems, see the following article for instructions to fix "my subscription payment failed" issues. 

Let me know if you need further help with your account QuickBooks subscriptions. I'll be right here if you need anything else.
