Myntra.com — return of a detected item

Address:	New Delhi, Delhi
Website:	Myntra

I purchased a thermal set from Myntra. Since I was happy with the product I discarded the original packing and price tag but when I wanted to use it I realised the electronic tag was attached to it. I have been requesting return/exchange but the customer care simply refuses to register the complaint. I have the innumerable phone calls recorded, they have simply asked me to get the electronic tag removed myself and point blank refused to register the complaint. Pls suggest how I can get justice .
