Pantaloons Fashion & Retail — Refund of failed order

I have made a purchase on Aug 3rd and I tried to pay the amount through PayTM. The amount 259 was paid from PayTM account and due to a delay from Pantaloon side, the order got failed. The failed order number is 3600662 and the transaction id from PayTM is [protected]. I confirmed from PayTM side that the payment was successful. I made so many calls and email to get the amount refunded but till now, there is no use. The worst experience in my life for a refund. My complaint number is COMP[protected]. Now, it is more than 40 days and I hope, they will refund the amount.
