Comparing customer service of Facebook to a mortgage servicer is tricky because of the value and the volume. Facebook has orders of magnitude (I'll get 10,000x more) content to moderate than a mortgage servicer where they really only answer questions when something goes wrong (3x every 5 years) the stakes are a million times higher.

The options for social media are really free (or cheap) to use and occasionally bad moderation or pay $5 per post or comment ($10 for risky ones) that see multiple human moderators to limit abuse and false positives. Or no social media. My point is the amount and quality of moderation people say they want is more expensive than they'd pay for these services, but there's still a lot of value to them, so we're left with imperfect moderation.
