Myntra.com — I have ordered a wildcraft bag from myntra but it has, been not delivered yet but its status shows that it has been delivered on 1st may.

Sir,
I have ordered a wildcraft women pink and blue printed bag on april 25 2019 by paying cash through upi app. I have waited till may 3rd 2019 as the app shows this date as the approximate delivery date. One that day i have shocked while checking the track status because it shows that i hasbeen delivered on 1st may.

I have registered a complaint with myntra's customer care and they asked me to wait till may 8 2019. Later on they mailed me that they have delivered the item with an attachment of a picture of sinature considering as aacknowledgement proof. But that was fake singature, it was not signed by me.
Again i called the customer care number again they are telling the same thing that they have delivered the package. At last they asked to wait 48 hours.
I want the ordered item or refund my money back.
I am attaching the mail they have sented to me
Please do the needful

Thank you
