Airtel — postpaid mobile

Airtel is showing me 14, 06, 249.80 rs of outstanding bill however my past bills are not more than[protected] rs. I called them bit they were bot able to justify this amount. This is a kind of mental harassment to customer and asking that please call after sometime.

For past several months i am facing this type of issues with airtel and infact that is why i ported on of my other number from airtel to jio. But this time it is amazingly ashtonishing.
Please help logging a complaint against airtel for giving me stress and mental harassment. Also wasting my time interacting wih there customer care.
