Bata India — refund not initiated since 1 month

Address:

Lucknow, Uttar Pradesh, 226021

I shopped from bata.in on 17 may and returned a product on 23 may and haven't received my refund till now. Even after making so many calls to customer service and receiving a mail to solve issue within 48 hours nothing seems to work. This kind of service is really unexpected from such a known brand.
