ICICI Bank — harassment calls from icici representatives

My name is dipti john i have been getting harrashment calls in my office landline stating that there is some loan that is unpaid. For your information i have no relationship with icici bank, still don't understand why are they calling. Now its hieghts they have been calling my friends and harassing them stating that there is a loan pending on my dad name. Funny part is that neither my dad or me got call on our cell no.. These calls are really annoying and depressing. The calls that they made were all to me and my female friends. No one has give you the right for harrasing people. Because of these calls i am in the verge of getting fired from job. Please look into this matter at the earliest.
If i still get these calls i would definitely go to consumer court.
This is the no that i am getting calls from +[protected]
