Zivame — refund for my returned product

Website:

Zivame

I ordered two bras from zivame which turned out to be completely different from what it appeared on their website. So, i returned it and they refunded the amount not to my bank account but as zcoins.
They have not clearly mentioned anywhere how to use these zcoins for purchase.
I regret having bought anything from this website.
It was a huge disappointment.
There is a reason why companies like amazon are so popular because they actually care for the customers.
Never use these small apps for purchase.
Regret having shopped from here.
You can get the same product that you see here at a much cheaper price at sites like amazon or myntra. Their buy 1 get 1 free sale are a big hoax. They double the prices and show it to customers.
-5 rating out of 5.
Terrible experience shopping here.
Shop at your own risk here.
