Bajaj Finance — daily calls for harassment for loans

Address:

Vadodara, Gujarat, 390008

I m getting daily 2 to 3 calls from bajaj finance.
I clearly mentioned to customers care not to call me.
But this people are not understanding and listening.
Please consider my request to explain them not to call me.
I don't know how can I make this shameless people understand.
Daily they used to call me for ove draft facility.
I repeatedly told them to deregister my phone number but they are not doing so.
Please interfere to resolve it as the calls are made by bajaj finance at very odd hours.
I m fed up... U
