Flipkart — Unable to open bill after downloading

Hi I have complained about this issue twice last week but there is no response. Please someone look into the issue of Invoice/bill not opening after downloading. Order no OD[protected]. I expect bill/invoice to be sent to my mail address very soon. This is just a poor service offered by Flipkart where customers are not able to open the invoice for their products. Hope to hear back from Flipkart service asap.
