Ajio — Ajio Scam - Received defective product but can't exchange even exchange is available

On 12th March I've ordered cloths of value Rs.5237. I've ordered a Allen solly black trousers but what I got is blue. Also I've ordered Allen solly blue shirt but I got a defective shirt. Ordered a jockey boxers but while receiving, it came with top and bottom opened and torn box which is the worst thing. I tried calling Ajio customer care for two days. Both yesterday and today the call gets cut while speaking. Firstly I thought it was due to network issue. But today too while asking several questions they cut the call. This clearly shoes the cheap strategy of Ajio. Is this the legitimity? While speaking with them they say like exchange is not available for your pincode. Delivery is available, return even available but exchange is not available to the same pincode? Really? Even their own mall and trends address were not available for exchange. I just need to exchange the defective products. Take action as soon as possible.
