I've placed an order (Containing 2 pairs of shoes & a 30L Hiking Bag) worth Rs.2097/- on[protected] from Decathlon, Gachibowli, Telangana. The order was confirmed by the store the very next day on 22nd Sep. Not even a single call I got from the delivery service (Delhivery) uptill now. I've been trying to cancel my order by various means but failed to do so as there was no option available in Decathlon mobile app. I've contacted "care.[protected]@decathlon.com" 15 times to cancel my order but got no positive response from them. They reply back asking me to wait for the call from Delhivery and then ask them to cancel the order. The problem is they never tried to reach me, never called me since this order is placed. Please resolve this ASAP. I just want my money back.
