Airtel — Charging more than monthly postpaid bill amount

I have received a billing amount of Rs 5820.94 for the month of October 2023 for my mobile number which is completely unacceptable.I am in USA from past 3 years and i have never used my Airtel number for calling but i have received this bill amount of Rs 5820 for incoming and outgoing calls and international roaming which i never used.
Upon checking the numbers which is showing in the itemized statement i can see the all the numbers looks completely SPAM[protected] and even the other all incoming numbers[protected],[protected] in the statement is SPAM and this issue has been already mentioned in the google page by other Airtel customers which is a issue from Airtel end that needs to be fixed.Also I am daily getting my international roaming pack activated without my knowledge and Airtel is not taking any action to fix.
