Reliance Mart — refused to sale merchandise

Address:

Jamnagar, Gujarat, 361142

I have been dedicated customer of reliance smart (Across from the refinery) for the last 4 1/2 years. On average, i spend around 5, 000 rupees/ week at this location. Today (11/17)- i visited the store to purchase my weekly groceries in which i was told by the teller/ mgr that i needed to apply/ have reliance card in order to make purchases. I asked kindly, "please let me purchase these groceries/ items which i need"; however, i was refused service. Please provide document that states when this policy became effective due to the fact i made purchases at this location last saturday (11/11) and i was not informed of this new policy. I checked the doors of the store for posted information and the reliance website; however, i cannot find any information on this new store requirement. I left the store feeling discriminated against and feeling bad for a store loosing sales of this magnitude in a market that is currently "cold" and sales are down. Please provide.
