Bajaj Finserv — emi card limit

First i was pleased with bajaj service, now i'm not satisfied becz. My card limit was 126000 from there it reduced to 50000. I paid all emi s on time even after this happens which i'm totally not satisfied. I have noticed online that same has happened to others. When i contacted the customer care they told me that, it's the audit department responsible for and they don't have any access to that. I request the bajaj department, when a customer is paying all emi on time increase the limit don't decrease it. Thank you.
