Bajaj Finance — wrong attitude towards customer

Address:

Kolkata, West Bengal, 700156

The customer care executive named "bhavna" is calling me again, even i told her that i am not interested in the overdraft service, then i enquired that how did she got my number, she started screaming at me and told from data, i told if i have not enquired how can my number be recorded in the database, then she told that data is stored in the computer. Then i told when i have told her again & again not to call, why is she calling me. To this, she replied, "put your number into dnd".

Can someone explain to her that without feeding the number in a database, computer cannot store anything of its own? And how can anyone tell me to do what?

Have bajaj finserve stared new advise expertise as well?
