I made two purchase of mobile, One from flipkart and another from snapdeal.I use payback platform from where I get points.they say it may takes one to two month for the points to be credited in to the payback account but its more than 6 months waiting for the points.There is more then 500 points which must be added into my accounts.
I think there may be bugs when doing transaction using payback.Its must be solve so that it must be worthy to use it otherwise no one remember opening payback website before doing shopping from E commerce websites.
