Website:	Indian oil extra rewards card

I am using my above said card for the past four or five years. I have encashed my points three or four times in petrol station. It was active till last july end. And i had nearly 240 points. For that i have a proof. Suddenly it was blocked and i called customer care several times and emailed several times. But till date it is not activated. I called the person incharged in my local office area also.
But, there's no response from indian oil. I request all the customer's not to buy this card here after. I think they purposely block if we use card regularly.
If it is not so, no one called me from indian oil and verified. Very poor and worst response from indian oil. They charged the card and make public to buy and if we use it, they block the card and make us to buy again. I think it is a great selling statergy. So, friends think before you go for it
