not only was it never what they said it was,

Ok, so it wasn’t actually oil made from snakes that they are selling.

what they said it was didn’t do what they said it did.

So actual ‘snake oil’ (as in, oil made from snakes) doesn’t do what they said their product does. But what their selling isn’t actually oil made from snakes.

So does whatever they’re actually selling, do what they’re saying it does?
