Poor company refund policies

I found it extremely disappointing speaking with the company, even though the helpline was friendly the companies policies are absolutely unfair. I tried to cancel or move my flight 4 days prior to the flight, the policy is a non-refundable air ticket purchase, which is fair since i agreed to this upon purchase however when asking for a voucher or some sort of way to use it at an unknown later date, they just kept on asking for what date. The problem is that I don't have dates yet each time you move the flight there are fees involved, and they don't allow a voucher or credit bank of any sort. This is extremely unfair! No matter what you do, you lose your money by paying for services you don't use. Though to them I my recommendation probably won't make a difference but as far as I am concerned they are not to be used for future travel again
