Rx3 rear wheel brake rotor

[Grandfather Frog]

Greetings from Athens Greece to everyone.

I have one quick question.
Yesterday i had a nasty fall and i managed
to crack the rear wheel break rotor in 3 different places.

It is still attached on the wheel but it is about to collapse any time now.
Also when it brakes, it makes a horrible noise
and the bike acts as if it has hiccups...

Any idea for aftermarket or compatible rotors...???

Thanks for any help.
