Patiala, Punjab, 147201

Hi.
I have placed an order of arrow shoes on myntra having order no.111885434048154194303. Due to size issues i decided to return the product. I have not received my refund after pickup was done. I received refund initiation mail from myntra & refund timeline has been passed & i have not gotten refund of returned product. Kindly take necessary action against myntra & refund my amount of rs.1650.82 as the required timeline for refund has been passed. I received refund initiation mail from myntra on 30 sept 2019 but the timeline of 10 days have been passed and still did not get refund..
