Firstcry.com — return not picked up and refund status says refund successful though no refund provided

Address:

600100

I have placed order for baby walker with firstcry.com (2063737sou8178823.)
I received the product on 13 aug but it was damaged so i raised a return request on the same day. The person comes and says he doesn’t have proper logistics and so refuses to collect it back.
I have raised many complaints but to no use. Still it has not been picked up
But now on 29 the august the site shows as refund successful but i have not receive it. They placed the amount in my wallet and immediately removed it and updated the status as refund successful.
I didnot expect such a cheating from reputed company like firstcry
Highly disappointed!!!

What should i do now
