Airtel — cant activate my sim through 59059

Address: 160062

I've ported my no.[[protected]] from vodafone to airtel and i've also inserted new sim but verification call to 59059 is not connecting. Every time i try to call at 59059 it automatically disconnects and also i'm unable to receive incoming calls to my number, along with this there's poor network signals in our locality. I couldn't believe how airtel is so weak in customer service.
