Vistara Airlines — Refund not received

Address:

Delhi

I purchased an airline ticket from Vistara airlines to fly to Kolkata from Mumbai on 6th November 2021. This ticket was cancelled and they sent me a notice that Rs. 3503/- will be refunded to my account. In last 2+ months, the amount was never received. After calling them multiple times, they keep on saying that they refunded the amount from their end and as proof they show a notepad [dated 6 Nov 2021] which I am attaching to my message. I went to my bank and confirmed that the amount was not received and that this notepad is not an admissible invoice. When I called them back (on 10th January), they told me I would receive a proper invoice within 24 hours bearing some bar code/QR code or an invoice number as a proof and the operator cross-checked my email address. This email was also not received in last week, as expected. They could only send an invoice if there were one.

Please do the needful, so that we get our money back.
