Myntra.com — Return of order

It has been a month since I've placed the request for return of the product as they have delivered the wrong product.
They had delivered the different product of the same brand.
Initially I had raised a request for an exchange but their delivery guy came at my house and said I have to raise a return request. Since then I've called them 6-7 times. The last time when I called them they told me exchange is approved from their side and I will get my product.
Till now I am waiting.
And on their website it is showing refund processed.

Every time I called them they give me new deadline when my query will resolve.
