How to appeal against an unfair decision - conference paper
What you need to do is to understand why your paper was rejected. I'm pretty sure your paper was not rejected from what you describe as "a top CS conference" for such obviously false reasons. Reviewers don't decide whether the paper is accepted or rejected: they advise the programme committee. The programme committee evaluates the reviews before coming to a decision and a review containing such obviously nonsensical comments will carry very little weight. If your paper was rejected because of the reviews, it was the other reviews, not this one.

Note also that, at top conferences, many papers are rejected simply due to bad luck. Usually, there are many papers that are a good enough quality to be accepted but the conference isn't big enough to take all of them. The actual reason for rejection may just be "We liked your paper and it's of essentially the same quality as papers we accepted, but there just wasn't room for yours and we liked these other ones just slightly more."
