Bajaj Finance — frequently interrupted by their call center in my daily life

Address:

560048

I took a bajaj finance emi loan about 10 years ago.

It has been my biggest regret. It is 2018, for the last 10 years, their call centers give me calls sometimes almost 2 times a day, offering new products. It has become worse now, with automated calling and some recording playing, offering loans

Same with my email, they keep spamming me.

Why do they keep harassing me like this. My important meetings are frequently disturbed.

I have told them several times to stop calling me, but they don't care. I keep getting calls from different cities and different numbers.

They show no respect for the do-not-disturb registry.
Please help me, get them out of my life.
