Airtel — Internet recharge issue

I've recharged my Airtel Broad Band serivice for 1 year on 28th Novemver 2023 using Airtel Thanks application. But its reflecting my account is showing its going to be expired on 24th April 2024.

I've called their customer care and inqured abouth this issue but they didn't provide me proper solution nor they extend my service period.

When I raised a ticket to refund the balance amount they closed the ticket stating its resolved without any information and refuding it.

When I called to check the staus they asked its closed I need to send email tothem for this.

I've send mail aslo but no response from the team.

Now they are asking me if I need refund I need to disconnet the service and wait for another 45days for refund.
