1. We had booked our vistara flight for 8th Dec with HappyEasyGo for travelling from Jammu to Bangalore.
2. Due to reschedule from the airline and the revised timing not suiting us, the airline agreed to cancel our flight for a full refund.
3. We raised the same with HappyEasyGo with a written proof from Vistara that they had already issued a full refund to HappyEasyGo.
4. Since then the refund status on HappyEasyGo is stuck and we have received no response from them on email or call for more than a month now.

Attaching evidence of ticket/refund status and email from Vistara.
