I ordered a tshirt from myntra it’s too small in size so i placed a exchange request but it’s showing my location unavailable for exchange of that product whereas new delivery of that product is available on my location what is this scam? I can’t keep wrong product with me i want exchange asap and i was tol disturbed by the delivery boy also even after answering him about my unavailabilty in town and i told him delivery date is on 1 march he started calling before 3 days and disturbed alot
