Airtel — dth late payment fee charge without notification

Address:

Chennai, Tamil Nadu, 600041

Airtel never posted any message of late payment fee charge of rs. 15 in any of its websites nor, in its terms paper where the user signs.

Why is this such a malpractice and such a cheap behavior with airtel. Why will they not even inform the customers that some late fee is deducted. Some warning message will at least make the customer to recharge on time.

Such a cheap behavior.
