Limeroad — tan slip jutis

Address: At- Kumbharpada, Near -Budhima mandir, ps-Dhanupali dist-sambalpur, Odisha,pin-768001

I had purchased a half shoe (Tan slip jutis) from limeroad online shopping site on march 2020 through cash on delivery, the product i received was not in my expected. Hence i returned that product on 08/03/2020 (Pickup copy attached). But didn't get refund amount.
So i mailed them to their customer care. And they reply that amount will be credited my bank account within 7 working days. But after 7 days i didn't receive that amount so i mailed tham again and get same reply 7 working days.
I mailed them several times and get same reply. Till date i have not received the amount in my bank account.
So i request you to kindly do the needful.

Thanking you
