[protected] this is just one of the numbers i get 2-5 calls every day without fail from bajaj finance, its been like this for over 4 years but the frequency has increased drastically for last 2 months - they just don't get it, i receive other calls also but once or twice, not like these guys, how to make it stop??? They have been telling me for over an year that they will remove my number fro data base it never happens, i hav enever done business with them how can they use my number, have also added my number to dnd list through vodafone, i am tired of these guys, especially calling at work time with different cell phone numbers
