HDFC Bank — life insurance policies

Address:

Jaipur, Rajasthan

Hdfc agent fraudulently sold 4 hdfc life insurance to my father-in-law, mr ashok bhise, jaipur (Rajasthan) saying that only one time payment is required as the time of purchase of policy. However now hdfc life insurance company claims that for consecutive three years the premium should be paid.
My father in law does not understand english properly and failed to understand the contents of the form of policy before signing it.
