I agree with Fiat Lux, the current rate for now in QuickBooks Online India subscription is INR 317 + 18% GST. This is currently offered for a monthly subscription since the annual billing is no longer available for our new customers.
In addition, are you done using the free trial in your QBO account? If the amount showing in your Billing & Subscription tab is ₹ 36000, I recommend reaching to our phone support. This way, they can check your account and trace the cause of the issue.
