Clarks — refund and customer support

Address:

Dhanori, Pune, Maharashtra, 411015

I bought a pair of shoes from clarks.in on 16th april. The shoes were a size bigger and hence i returned them on 20th april (On the next day of delivery). However, i have not got the refund yet although it is three weeks now. The status on the site says 'refund initiated'. I have been trying to connect to their customer support but it says 'our executives are busy, we will call back'. I received a call back. I have sent numerous emails but did not reveive any reply. Not even an acknowledgement. It is a clear case of fraud by such a renowned brand. They don't even have a grievance cell. I tried to reach out to their management on linkedin but haven't received any reply yet.
