Airtel
Late fee charged, but payment was made on time

I am sunil ostwal holder of airtel no. 9829073021 since last 10 years. I paid my bill on 27.04.2010 of Rs. 300 which is my last date for payment. But in my 27.05.2010 last date of next bill payment, late fee is charged for late payment. I am having the receipt of the Authorized bill collector for airtel. Further I paid Rs. 350 on 27.05.2010 i.e. the last date for payment. I am having the receipt of Airtel money collector also. But again Airtel confirms the receipt of payment on 28.05.2010. I will go to the consumer court and also file a civil suit on Airtel and Its money collector.
