Reliance Prepaid Mobile — Regarding Online Recharge

I had made an online recharge of Rs. 496 on 19th Sept'08 on a scheme of all india Relaince to Relaince free. But that scheme was stopped by relaince so they did not recharge it. On contecting the customer care of relaince on the same day, they had assured that when such thing happens, the amount which is debited from your account gets credited back to your account within 48 working hours. Today is 22nd Sept'08 and still the amount is not credited in my account. On contacting the customer care of relaince today, they bluntly said that the money is gone and u wont get it back.
This is not fair. Can i get my money back???????
