I backed two projects, but in first I got what was promissed, it only was not what I think was promissed, and they was onest about it, and said it that they think they can do better, but they delivered both the goods, and their sorry.
But Calyos delivered only false promisses, and fake deadlines. If they would come at first missed deadline and said sorry we can not make it, situation would be completely different, but they just promissed another fake deadline.
