Airtel — cheating and overcharging

Address:

New Delhi, Delhi, 110017

Airtel team is misleading me and harassing me for making due dayments.
And today my number is disconnected.

I had already paid bill no – ft[protected] – dated 12-sep-2019- amt – rs.3232 (Previous balance – rs 820 = total rs. 4-52.63)
Payment detail (Amt rs 4052.63 date[protected] – account no – [protected])

Above bill was for advance rental from 6-9-19 to 5-3-2020

After this payment i also made another payment of rs. 351.[protected]

Despite making advance payments i am being harrassed and called regularly to make payment...
Its clear case of cheating and fraud...

Do the needfull... And also i am filing a legal complaint for this
