'Complaint' in the Bible

Now in those days, when the number of the disciples was multiplying, a complaint arose from the Hellenists against the Hebrews, because their widows were neglected in the daily service.

Therefore also I came without complaint when I was sent for. I ask therefore, why did you send for me?"

bearing with one another, and forgiving each other, if any man has a complaint against any; even as Christ forgave you, so you also do.
