I've ordered a necklace from meesho of 133 price. seller name munmun's at 1:49 am and choose google pay as my payment option and my money is deducted but the seller didn't place my order please help how can I get my refund.
Meesho is a bad app i don't know where to find help as I've email meesho but they didn't respond.

There's no way you can talk to seller or anyone for help such a bad app.

I've attached my proof of payment and email that I've received. kindly take necessary action.
