did something stupid

[tt-01 mamba]

hi,

i just did something very stupid, i plugged my MM in the wrong way
i think it has toasted the board (grew very hot very quickly) will CC still replace this if i pay my $50 ?
I've also soldered my own switch onto it, (a big one from a teu101bk esc) so will i get that back if they replace the unit or should i clip it off?
