Pepperfry.com — cheat company in regards to 7 days return policy

Website:

www.pepperfry.com

I ordered 2 products & got both faulty products.
1 product is very silicone ironing mat which is very stinky which is definitely a manufacturer defect.
the other product is mentioned as quantity of 2 with medium size but i received 1 quantity & that too of small size.
i sent many mails & complaints but i got only 1 mail saying that above mentioned problems are not their problem so neither they will do reverse pickup or refund, nor they will send the short quantity of the product.
now when i am raising complaints, i am unable to raise complaints.
in all, the site is cheating on the name of return's policy but actually is not doing fair things.kindly check the whole fake system if any concerned person is taking care.thanks
