Bajaj Finance — frequent auto calls for loans

I stay in pune and had purchased led tv through bajaj finserv.
My contact number is [protected], my problem now is i'm getting frequent automated/manual calls from bajaj finserv almost 4 to 5 times a day, the same call and the same subject on low interest loans! These automated calls are coming irrespective of times and also all the days including holidays! These calls are really disturbing me a lot and sometimes more and more irritating, recently i purchased washing machine and laptop and you know what, i opt for hdfc rather than bajaj even though your scheme was better than hdfc. I am spreading awareness within my colleagues for not going with bajaj. I request you to remove my mobile number from your systems and help me to avoid these nuisance calls please.
