This is a clear case of harassment. I received a mail from airtel to pay Rs 5662 on 31st of october to clear all my dues with a waiver. I did the same on 2nd of november. I have the copy of payment receipt as well as mail I had received from airtel. But now they are again calling me up and saying that rs 10000 is still left to be paid.This is pertaining to phone no. 8527141212
