InputMismatchException when attempting to run program again in do while loop

Having successfully created a policy holder and writing the information to csv I try to run the program again using a do while loop but receive an inputmismatchexception after typing surname.

Can someone point me in the right direction or advise what I am doing wrong with this piece of code?

Here is example of what happens... console

I am able to complete a first run but do while loop fails when trying to add another policy holder.
