I do not have a question nor I need an advice,. But I will give you and Onion an advice, from old entrepreneur to young entrepreneurs:
Your lack of communication does not show that you run a professional business.
Take yourself an hour of time, and give some feedback to your customers - even if it is not a positive message.
Communication on Kickstarter was a catastrophy, but communication on Indiegogo is just not existing. No backer of Kickstarter or Indiegogo knows if Onion is a serious company or just a hoax.
So please: Provide regular updates to customers on BOTH platforms, and look into freshdesk for open incident tickets.
