Myntra.com — Product not reshipped but Myntra claimed product reshipped

I ordered a dress from Myntra but because of size issue and defective product i return it. But quality check failed and return will be reshipped to me but Today 7th days but product not reshipped. I contacted to Myntra customer care they told me to wait for 24 hours and from last five days they only advice to wait for 24 hrs but not giving satisfying reply.

Product not reshipped also my amount is stuck.

Please help in that case I don't want defective product.
