Idea cellular has the option of payment by direct debit on credit card. U might have opted for that option when taking up ur mobile connection. I had faced the same issue. I did not know that i had opted for direct debit on credit card option till i got the amount reflected in my credit card statement. After facing some trouble, I disconnected my idea mobile connection. Having said that, u cannot blame on the credit card, but u have to change ur payment option for ur mobile connection Thanks, Mari
