Bajaj Finance — Harassment through calls

This has been happening every day for the past 4 months
- I am not a client of Bajaj Finance, yet they keep calling me on [protected]
- I never signed up or tried to connect with Bajaj Finance. They keep calling via an automated caller. It's not even a person at the other end. Moreover, even if I decline or ignore the call, they call again after 15 mins. The frequency of their calls equivalent to harassment. If I decline one call, they dial again from another number. I end up receiving multiple such calls in the middle of work.
There is no way to complain, their grievance number is not reachable and it's shocking that they are allowed to harass people in this manner
- I request to be removed from their call lists and do not wish to ever partake their services, even if I am in dire need in the future
