Airtel — complaint] - international roaming activated by airtel without my explicit approval and additional charges levied

Airtel charged additional amount for the previous billing cycle by surreptitiously activating international roaming without intimating me. Both my primary and add-on sim cards seem to have been charged this amount. I have used matrix sim card for international calling and data purposes in the usa.

I travel regularly abroad and this has never happened to me earlier. It is appalling that after calling their customer care and visiting their physical store yesterday and talking to nodal officers today i have received no satisfactory resolution. I am being coerced into paying.
