Lic — want to remove agent from my lic policy

Two years back, i bought an insurance policy form an agent, once the documents signed and payments are done, she refuses to take my calls and even stop responding on whatsapp.

So is there any way to punish her or teach a lesson to her so that she cannot repeat the same thing with others.
Is there any way to remove her from my policy. I don't want her bank account get populated with my money all the time without providing any service.

Any help or suggestion really appreciated.

Thanks
