Coolwinks — money back

I have purchased eye glaases online. There was offer of 100% money back after 14 days that is after return period over.

After placing order on 9th may i asked them by call that am i eligible for money back please check and tell?
They told me that i am eligible.
After 14 days of return period. I didn't receive my money. So i contacted them they told me you money will ve processed in next 48 hours. But i did not receive in 48hrs.
So again i call about the same. They told me you are eligible and you will get your money in next 72hrs. It is taking time due to technical error. We have already processed your money.
I have recording of various call saying that i am eligible and they have processed.
But even after passing that 72 hrs. I didn't receive my money. So i again call and their senior executive mr sarabjot singh told me and convinced me that my money will be credited in next 72 hrs. It is delaying because technical error. You are eligible dont worry. You will get your money. If it will not credited in next 72hrs. We will try to proceed it manually.
So today on 5th june 10 am my all time frame provided by then is over.
And i called them why money is not credited yet.
They told me you are not eligible for money back. They wasted my 8 days for just begging my own money..

In their terms and condition they mentioned that you can not use coolcash (Their own wallet money) and any coupon code for to use this offer. And i did same i haven't used any of them. And even confirmed after ordering so that if i am ineligible so i can cancel it asap.

But now they are refusing to give my money.

And they have removed that offer description from their site.
That offer was for period of 9th may to 12th may only.

Please help me in this case to get my money. Back.
I can return their product in 14days only. But they already told me 2 3 times that i am eligible so i have product with me.

So i am requesting you to help me.

There are lots of people like me are suffering from the same case. You can chek twitter of coolwinks.
I have call recording of my talk with executive claiming that i am eligible.
Please find any simple way to get my money back.
