Vodafone Idea — ] Vodafone idea(VI) tele verification number 59059 not working in roaming

I ported my airtel number to vodafone and i came into roaming. Now when i call 59059 it aaya that number is incorrect. I have tried customer care multiple times but they don't provide any solution.
I am in trouble as it is my primary number that is used in banking. Please suggest any solution.

I visted vi store in kerala and taminadu . they gave a different sim and that did not resolve the issue.
Karnataka has put travel restrictions for kerala. due to which i cannot go back to my home circle
