“Two things that really bug me about their service is so much of the information is incorrect and unless you are mormon you can’t get them to correct it.”
They don’t create records, they just publish them from church or civil registers, or family trees submitted. You should not rely upon somebody’s family tree unless they published their sources. It’s not reasonable to expect the LDS to verify every family tree submitted to them.
Sure, but even when you have proof they will not change their records.
