Airtel — Unable to call for tele verification

I have ported mi idea number [protected] to airtel on 29 jun 2020. I got the airtel sim after 4 days of the port request. I have been trying to dial 59059 for airtel sim tele verification and action but it automatically gets disconnected. The sim shows either roaming signal or emergency calls.

I tried to call airtel operators at my location but they are not helping me to resolve the issue.

Please help me get my number activated it's been 3 months now.

I had complained about this on 12 jul 2020 but it's not yet resolved.

I'm surprised that airtel is not at all listening to customer problems.
