Vodafone India — not getting incoming std calls from airtel after porting

Hi,

I ported my number [protected] from karnataka idea to karnataka vodafone on 18th april, 2018.
After porting, i am not getting any incoming std calls from airtel. It's telling that number does not exist. I got to know about the issue when my family could not reach me and it has been a week now i am following up with vodafone, every time they are telling it will be solved in 24 hours but they are not doing it. I went to vodafone store also but there is no hope. Now i can not even report my number back to any other network. This vodafone promises of customer delight and this is how they treat their customers. I am missing all the emergency calls as i do not have alternate number also. This is how vodafone plays with it's customer.
