All I know is-
1) Moses complained, lost his temper and was denied entry into the Promised Land.
2) I think it was Elijah who complained about being the only believer in God left and that he was all alone and ended up reaping a whirlwind for it.
3) The one person who had every right to complain, being Job, didn't. He just wanted to know why all the bad stuff was happening to him.
