Unfair Cancellation

I had this insurance from November 2012 till now. I have called the insurance company to add on my existing policy and was asked if any member of my household or myself have undergone debt reviewing counseling and I am currently under debt review and it resulted in them cancelling my policy at the end of the month (30.06.2015). This was not disclosed on my policy schedule and would want my premiums to be paid back as this was not disclosed from the beginning.
