Myntra.com — Invictus men charcoal grey and black slim fit checked single-breasted smart casual blazer

I ordered an Invictus blazer on myntra but due to size fit issue I went for a return and gave it to the delivery boy in the same condition as it was. Some days later they notified me that my return was rejected and sent it back to me. I talked to costumer support where they told me that there was no price tag inside. But when I opened it the price tag was already there. They say they have raised an issue but nothing is working. Now I am helpless I want my money back.
