Bajaj Finance — receiving daily unwanted calls from bajaj finance

I am receiving unwanted calls from bajaj finance tele callers every day to my number [protected]. I have requested them numerous times to remove my number from their list. I am getting calls at least once a day since more than 2 years. It is so annoying to get calls from different numbers when we are busy. It is really frustrating. I have registered for dnd, but it didn't help.
I hope registering a complaint here would help me.
