I wanted to buy a book from an online seller Flipkart just a while ago.
I found the book and tried to place an order and the screen simply froze after I entered my email address as required. I tried this a number of times and finally in exasperation went seeking help.
That was another nightmare as this particular problem is not listed in their alternatives of problems listed and there is no way to talk to them to explain. The only way I could contact them is what they call ‘the old fashioned way’ by mail.
I simply gave up in disgust and found another online seller.
