[Resolved]  Vistara — Refund for cancellation of tickets

I booked 4 flexible tickets ( 2 onward and 2 returns tickets L89KG8 ) on Jan 11 2022 with vistara for flying from Germany to India and back. The tickets costed me 1, 58, 160 rupees. On Jan 16 2022, I cancelled both tickets. I received an automated email from Vistara that amount of 1, 57, 678 would be refunded to me to the same payment source. I did not get any money till now. I called Vistara multiple times. They told only that amount is refunded on 16 Jan 2022. They sent me 2 notepad files which were of no use to the ICICI bank as they cannot consider this as a proof of refund. I have been trying to reach Vistara via social media platforms too however they are not giving any response or taking any action. Customer care told that they will escalate this 2 weeks back however I didn’t receive any email or call from them yet. I am being duped of my money just in same way as the previous complaint I saw here. This is a pattern and Vistara should give a proper answer .
