How to disable vim's indentation of switch case?

I'm currently fighting with Vim, I can't seem to make the indentation options do what I want.

Here are my settings, I put them at the bottom of .vimrc to make sure they take precedence. As you can see I'm going a little crazy, so I tried turning off almost everything:

set cindent
set cinkeys=o,O
set cinoptions=
set cinwords=
set indentexpr=

In most cases it seems to work fine, it does one indent after opening a block and everything is fine. But there is one case that is driving me crazy, when there is a { after a case statement, the next line is way too far indented:

switch () {
    case CASE: {
                   // <-- next line gets indented to here, why??
        // <-- should be indented to here

How can I make it stop doing this? TIA
