Bajaj Finance — Wrong phone number tagged to a loan account

Address:

Pune

I have been getting regular calls on daily basis from Bajaj Finance
from last 2 years about a loan repayment, which is supposedly taken by a person called Shivraj, some how Bajaj Finance have linked my phone number to the loan account and I am getting daily calls from them to pay the loan.
I have informed them like 100 times that this is wrong number and they should update their system still they have not done it. Now the calls are getting rude and sort of harassments on daily basis.

Even these guys are sending message on whatsapp without consent about this loan which has nothing to do with me. I know from the whatsapp text about the loan account number its 4170CD93782561.
Please for god sake update your database and remove my personal number from records.
