Airtel — regarding tell verification

Hi idea,
I have port my number [protected] on 19 december 2018 and in evening i got sms on my alternate number to activate sim by calling 59059. From that time till date i am trying 59059 but it is not connecting.

When call airtel support and tell my problem they wouldn't talk logical and keep on saying pls try calling 59059. I think these less skilled resource just work like parrot and only say single line and don't give logical answer nor try to help.

I am every day getting sms on my alternate number to call 59059 and get your connection activated but 59059 is not connecting. Pls provide any other number or activate services of my new airtel number [protected]

My alternate number is [protected]
