Bajaj Finserv — Products activated without my knowledge

Address:

bangalore

I have recently taken Overdraft facility from bajaj finser, however I am extremely unhappy about the service. I asked for 1 product and without my knowledge they have activated so many products and charged me for the same. this is a good way of top up sales, however this is completely unethical.
I am trying to reach customer care for support however Its highly impossible to reach the customer care and when we send emails we get no response. First of all they activate products without knowledge, and when we try to use the facility it does not allow us. This is very pathetical and unethical .
