I placed an order of a lahenga of rs. 1799.00 on 7th may 2019 and with faith i did prepaid for the dress. The money is transferred from my bank account to payu (As the site payment process). But, neither there is any order placed nor any type of notification or messages i got for dispatching the order. I am so disappointed with this. Now i want my money back or refund.
