Bajaj Finance — Regarding spam calls and messages from Bajaj Finance

I'd like to make a complaint wrt Bajaj Finance group wrt promotional calls and messages which are multiple in a day, right in the middle of important office work, and don't stop despite mentioning many times that I am not interested, these calls and messages are a big bother. They keep calling despite the fact that i have full DND on. They don't seem to respect that either . My number is [protected]. These calls and messages need to stop immediately.
