Indiabulls Dhani — Subscription fee

Hi,
Loan account no: CL22767802
I paid all my dues and also canceled my subscription plan in January
but today March 14, I got a call from Dhani ( +[protected] and she said I'm due now of rs 353.
I said, I paid all my Dues and also canceled my plan in january.
Then I opened the Dhani app told the Dhani employee that there is no due, and the App is showing "Activate now".
and she said, "To view the Due amount you have to Activate the Subscription Plan". and the Activation plan is rs 353.
is this a scam?
I don't want to Activate the Subscription again, please stop calling.
