Vodafone — incoming calls from vodafone idea numbers blocked after porting from vodafone to airtel

I ported my number [protected] from vodafone to airtel on 27th june 2020.
After that iam unable to receive incoming calls from vodafone idea numbers, it says number does not exist. Calls are coming from all service provider numbers except vodafone idea.
I raised a complaint regarding this to vodafone, reference number c004-[protected].
But still my issue is not resolved. Iam missing out my important officials calls.
Kindly unblock my number so that i can receive incoming calls from vodafone idea numbers.
