Be thankful that you able to refund your money. Some other project out there suddenly disappear after realizing that their project will failed. Thats why escrow is important on looking for a good project. What ever happen to the project, even if it failed you can be sure that you will get your money back.
agree, out there are many projects that just disappear because they are a scam. so they are looking for other projects. for they also want to get profit again. so my advice if you want to join the project. do research first, because I am afraid you become a victim of fraud again.
