This is my update to the initial review. After staking ZIL for some time, I have earned rewards and I have tried several times to claim it, but it was unsuccessful. I do have extra ZIL available that is not staked. I have changed the GAS fee for something more appropriate than recommended and nothing. As a matter of fact, I was still charged GAS fee for the transaction that never happened. At this point I wanted to unstak my ZIL, but I can't before I claim the rewards.
