no it's not. it's only against the law if they advertise it, get you to show up then offer you something different and more expensive, that's a bait and switch. this would be them advertising something, then removing the ad on account of a production problem or something, they're not directly driving you to another more expensive product, and thus it's not illegal. companies advertise stuff all the time then adjust it or remove it if the product will no longer be available as they'd previously advertised, it's not illegal and it makes you look like an over privileged whiney 8 year old.
