There was a notable incident years ago when they messed up a billing script and precharged a year's service to all their customers, to the tune of $7.5 million. I'm not sure I've heard any horror stories since then behind the usual shared hosting things.
To be fair I contacted them after this incident because exchange rate shifts plus fees meant I lost money even after they unwound their transaction, and they immediately credited me the difference rounded up. No "please send us proof" no blaming someone else. Just money in the bank immediately.
So whatever else somebody at Dreamhost understands that "sorry" is not just a magic word that makes things OK by itself.
