Airtel — Refund of balance amount - [protected](Account No)

We have taken Airtel Broadband connection at shimoga on 04.02.2022 by paying 6months amount of Rs.3534 on 03.02.2022, after that we have transferred to Bangalore on 18.04.2022, we had a balance of Rs.2014/- in our old airtel account, initially airtel people told it will be transferred to New Bangalore account but after 2months they are telling it will be refunded and they asked to share Account details where we need to get refund after providing details and several follow up mails and calls also we are not yet received the refund amount, we have lost so many valuable time for this...Every time we have called to customer care they will tell to send mail again and wait for 7days but we have passed so many 7 days but not resolved...After several mails also we are not getting refund amount and not even reply for our mails also...Worst service… They will call for payment but they will be back for the customer complaints and the resolutions...This is not the good practice for such big organization.
