Myntra.com — Fake pick up

I have ordered 4 items from myntra.I ordered it by verifying their return policy, as the quality was very poor I requested for return. One day i got a message saying the will be done today, I even took leave from my office and waited for them because the item was expensive. At night I called the guy and he said he is not able to pick up the item. Next day I got a message saying pick up failed as iam unavailable. I complained in myntra. They asked Mr to wait for 2 weeks to resolve the complaint. So I waited 2 weeks, in between one guy called me and he said the adress which I was given is from kerala, at the time of delivery they didn't had any confusion of adress, and I have the adress... At the end of 2 weeks I again called myntra they said I have to wait 48 hours, even though I was angry I waited... And I called 2 days after... This time also they are asking me to wait 48 hours... I don't know what to do... My money is stucked there.. They are very irresponsible. I don't know what to do
