Air India Express — Delay for refund

Address:

shereefmanzil 691312 pathady

I booked a ticket on 11th April 2023 to travel from TRV to DOH and the booking was canceled within a few minutes after I received the confirmation mail, I contacted Tia, and told me that. An error in the system and payment will refund within 7 days so I booked one more ticket for the same destination this ticket was also canceled without confirmation mail. But these two cancellation refunds have not been credited to my account yet.
Several times I called customer service they give me different times to get my refund.
Please consider my request and do the necessary to get the refund as soon as possible
