Club Factory — refund not being initiated

Address:	Kamrup Metropolitan, Assam, 781029
Website:	club factory

I ordered a dress from cf which I got early before the arriving date but I had to return it because it was not up to my expectation. I requested for a return and picked up. The product was picked up more than five days ago but till now no refund has been initiated to my account. I called up customer care many times but no response from them at all. They always keep me on hold. These are my order details.

I request cf to kindly process my refund.
