[Resolved]  Big Bazaar — product not available

I went to big bazaar on the first day of the madly advertised sabse sata din(3 days)...in the last week of jan09.
the advt. had come in the newspaper highlighting the products which were on discount .there was an item ----ltous kaajal (buy one get one free).I went on the first floor of the thane(w) branch and asked for it .they did not have it ---imagine!!! there was arrangement for the mad rush which they were expecting anf they did not have the product.the lady on the counter told me the stock hadnt arrived ...and that the available stock was at 15% off only.
she had no clue that any such discount was on that day .If any of the co. personnel are reading this can verify it from the store .
what compensation can the store give to such customers???
I have lived in the US and the policy there is to give a raincheck when a advertised product is not available in the store to pacify a customer..
the customer can show the raincheck on the next visit and pick up th product at the discounted price.that way the customer is not cheated...

kindly look into the matter!!!
