If it doesn't seal after you try the sealant which they told you not to try (although it most likely will) you have little hope of them returning or supporting you further.  I'd return them all and go get something else. I'd recommend some Toto toilets. I've always done well with Kohler but these seem to be bad.

They woud have replaced the tank without me needing to return the defective one so that's not an issue. I would have gone Toto but I needed them fast and couldn't wait the etra days for them to come in. Kohler used to be my goto. Support was very good though it seems quality has gone downhill.

I ended up doing B, along with Dremeling off a high point on the rim of the hole that was cocking the bolt a bit, plus lightly chamfering the hole edges and lightly sanding the inside of the hole itself. It worked. I was prepared to silicone it though, it's just an opaque fishtank after all :-)
