made payment immediately by credit card

I made the payment of Rs 571 by cheque for datacard for month of Sept ‘06 (18/10/06). Realising that the cheque is not honoured by the bank, made payment immediately by credit card and the same was reflected in the statement of subsequent month (29/10/06) and outstanding balance was shown as nil. But to my shock got the lawer’s notice on 18th (dated 14/11/06)to make the payment within fortight!
