Does the 25% cashback on the Airtel Axis Credit Card apply to Airtel Black bills?

Hi all, I’m considering combining my Airtel services into Airtel Black and wondering if the 25% cashback applies to the Airtel Black bill as well. I assume the cashback is valid at least for the postpaid bill—please correct me if I’m wrong. If anyone has experience with Airtel Black or this cashback offer?

@AleenaJacob Yes, it works! I use my Airtel Axis Credit Card to pay my Airtel Black bill every month and get the 25% cashback.
