Bajaj Finance — bajaj finance spurious calls

Address:

560037

I am getting daily 4-5 phone calls or messages per day from bajaj finance on my number [protected], even though i registered and re-registered for full dnd. I have complained my telecom operator vodafone as well as the trai, but this doesn't seem to stop anywhere. Not sure what to do next. Here are few of the numbers that i have blocked on my phone block list still they are calling from new lines.
