Crowd farming by Openfield Poultry must refund us

I invested money in Openfield Poultry in a system they called crowdfarming. They had a chicken crowdfarming strategy that they didn't thoroughly plan for, people invested because they liked the idea and now Openfield Poultry is not paying us our monies whereas the investment period is completed. The last update they gave on Telegram was that people will be refunded by 30May2019 and that has not happened. I introduced people into this, we want our monies back.
