Bata India — Shoe return and refund

On january 31st i ordered a shoe and i had to return them due to size issue. I got shoe on 5 th february and immdediately i planned for return due to size issue. After continuous phone calls and followups and mails it took me 15 days for the pick up guy to pick my shoe. No customer service executive is clear with information. And today is 27 i havenot received my money back and they are simply saying 48 hrs from more than 7 days. Hell with the service useless bata..
