What exactly did you think you were doing when you backed the Kickstarter?
Kickstarter is not an online store that you buy something and it just takes a long time for you to receive.
You are essentially investing in an idea and in a company. You have to do the due diligence to make sure you are comfortable with the risks involved. That’s why, in theory, you pay cheaper than you would once the product launches.
You should know what you are buying into before you do it. If you are not comfortable with the risk, the course of action is to wait until the desired product/service hits the market and is actually sold somewhere.
