Of course they did not pay. Just keep on prolonging everything because people flocked back to them when they came back up. They have committed to paying 10% back with no timeline on the rest. Ridiculous if you ask me. They could come back and say 10% per year for 10 years. The only way to force them to pay is to stop using them till then start payouts. What is there incentive to pay back in a timely manner if everyone keeps using them?
They don't give you payout timeframe estimates because they don't have the money to pay out, duh.
They need people to mine and pay them their high fees to accumulate enough to start paying back over time. Without enough miners they cannot commit to a timeline. Sounds pretty logical to me.
