My apartment has mold on the pipes can I get out of my lease?

So I’ve told maintenance about the mold and showed them, they came and they didn’t fix anything just the hole that was in the pipe but didn’t do anything about the mold

In his words “it’s normal to have mold when it’s leaking water” and just left it like that and I’m like okkk.... so ima just sit here with mold on the pipes in my apartment .

Can I get out of my lease for this reason with no charge since they aren’t fixing that problem ?
