Airtel — Six months of delay in refunding the balance amount

Hi Sir,

I've surrendered my mobile SIM on April/2023 with AirTel and AirTel has sent me the refund cheque dated 7th June/2023 for the balance amount INR 442.88 (attached the letter and refund cheque from AirTel). The refund cheque could not be deposited in HDFC Bank, as the name on the cheque was incorrect (against the ID and Address proof submitted). Hence, I'd requested Airtel to reissue the cheque with name correction. I'm still waiting for the refund amount for the past 6 months, just for the reissue of the refund cheque with name correction and I've shared all the requested proofs and evidences. So far, the amount is still not refunded or credited to my account via NEFT. Can you please help me to get the refund amount with compensation and interest for the delays and the frustration undergone?

Kind Regards,
Suresh
