[Resolved]  Idea Cellular — allotted my phone number to a different person

I had a reliance sim. Suddenly the signals stopped coming as the company got shut. After 2 days, reliance users were on the vodafone network. I tried porting my number to airtel, but when i reached airtel office to get airtel sim, they said that my port code is still with vodafone and only vodafone can port my number. I asked vodafone to port my number, they said that my port code is with airtel. They blamed each other and none of the both helped me. After 2 days, they cancelled my port request and alloted my phone number to a different user on idea network. My phone number was linked with my bank account, aadhar, pan and i have been left handicapped without my number. I am student and i have submitted my number in examination forms. I have my whatsapp account on that number since 4 years. I have been left handicapped without my phone number as people related to me cannot reach me and even colleges, institutes, bank, cannot reach me or contact me. I want my phone number back as idea has no right to allot my phone number to a different user if the company has shut down. Please look into it
