Landlord problems what can I do?

So upon moving in my landlord said she had stuff In the garage. Which she was moving the stuff out of it’ll just take a little while. So I said okay. Well recently she keeps coming and grabbing stuff everyday. And going through everything she says she’ll be putting more stuff in. So I said when will we be Able to use it? She said she didn’t know and I said well we pay 1250 we should be able to use it. Apparently she’s trying to say in the listing it didn’t include the garage? Which it never did and the lease doesn’t say anything about it. What can I do about it? An she said my family ( because My room is upstairs) will have to live in the garage for a few weeks while she expands the roof..😳 does anyone know if she can do this?
