Referendums aren't the same thing as elections - they don't come with a set of manifesto promises or a promised programme of government afterwards beyond carrying out the policy suggested in the Referendum.

The politicians making the promises may not even be in the government (it tended to be Leave.EU and Farage that focused on immigration, Vote Leave was wary of doing the same and focused on the economy). All politicians can do in a referendum campaign is talk about implied benefits one way or the other.

It's now up to the politicians to work out the best deal for our country. It's going to be a much smoother ride (and much better for the country as a whole) if free movement of people is allowed and we join EFTA than if the government tries to hold firm on that one, for sure.
