My number which is active is issued to someonw else.

Sir Help me i am stuck in very bad condition. I have requested a port out from vodafone on 2-6-18. On 8-6-18 i have submitted my document to jio for porting purpose. Sir on [deleted]:00Pm i have recieved a call from vodafone postpaid care, and then i accepted postpaid request for my number as i was not sure that my number would be transfered or not. But Sir On 12-6-18 time 7:10PM recieved a sms that the number is successfully transfered to jio from vodafone. And from that time I was using Jio as my service provider. Jio is far better service provide than vodafone as they provide value for money. But Sir 2-7-18 I recieved a sms saying that my postpaid connection is now active. Tell me how can this be possible 1 Number 2 Different provider saying that number is active. This thing was resolved at that time but today 3-1-2019, I recieved message from vodafone, i was shocked and when i download vodafone app to check whether it is true or not there it is mention that my number is active. When i contacted vodafone through app chat section they said that number has been allocated to someone else. But this number is already issued on my adhar card from june. How can they provide the number which has been ported out to someone else. Please help me with neccassary points. And can i take legal action against them. Help me out
