Dealswap Store — Completely different product with no response on return request

I ordered a set of bralettes from this company called "DealSwap Store" but to my absolute disappointment, I received a product that was completely different from the product image on their website. I e-mailed them regarding a return but since the past two days there has been 0 response. I am a struggling college student and 600rs is a lot to lose. I need my money back.
If somebody with a similar situation knows a way please let me know ASAP.
