Vodafone India — tele verification for sim activation

Ported my sim from delhi circle to mumbai circle.

Got a sms on my alternate no [protected] on 23rd august 2018 to call 59059 for tele verification.

I am getting signal bars but 59059 for tele verification is not connecting.

I tried calling vodafone customer support who were of no help.

I have manually selected the network, restarted my phone, used a different phone but the call is still not connecting.

Any help on this will be really appreciated as this no belongs to my wife who is currently in delhi and now unreachable directly as a result.

Thanks.
