Airtel — my prepaid number [protected] is deactivated, not working currently

I am in Tokyo, Japan currently.

On sept 10th, I recharged 446 plan 90days validity [international roaming]

Since 2 days, sim is deactivated.

I sent mail yesterday to [protected]@airtle.com and they are telling me to authenticate my email id and have sent a link.

I opened the link to authenticate, it is asking for OTP to submit.

I replied back to [protected]@airtel.com saying that how can I authenticate when sim is not in working condition and not receiving any messages.

But those dumb idiotic people are just sending mail to me asking to authenticate.

How the hell I can authenticate when I can't receive OTP and sim is deactivated.

Please use your common sense and resolve this issue.

Thanks
