Icici Lombard — Wrong ncb notice

Address:

Jaipur

There has been a ncb notice issued to me wrongly by icici lombard.
Stating that i do not qualify for ncb benefits and therefore i need to deposit the ncb benefit amount to icici, failing to which my policy will not be valid.
I have complained for the same to icici bank but still there is no responce from icici bank.
I did not expect this from icici bank.
I dont know what to do next
