Echarge coupan is not valid

I have bought an idea recharge coupon of Rs.20 and recharged my account, But the reply is that the number that I have entered is not valid. now the retailer has refused to grant any compensation.

Try to solve the problem as early as possible and recharge my account with the respective amount: SL no of that coupon is 300000000060710791 and my Idea mobile no is 09592763725
