My paytm order id with #[protected] was expected to get delivered by date given was 15th aug but it wasn't delivered and now the status of the order is delivered but i didn't received my order. 10 times i called the pay tm customer care helpline.. Everytime no one attend to resolve my issue. Do something about this or i will have to file a case in consumer court. I have ordered 5 items altogether out of which 3 items was delivered but the rest items weren't received
