The worst of its kind marketing gimmick is the payback site. It only shows how to earn points but those points are never credited. It makes you to follow up like a hell & finally after months of pursuit they reply very lightly saying -
Sorry the points cannot be credited as our partner does not agree to the transaction or as a matter of business policy we do not have tie up with this particular outlet/product. Its not at all a payback but its a take-back in terms of our various resources.
All those who have experienced it please support a voice against the much hyped- payback schemes.
