Type out your account of the entire incident in Malay if you can but English will suffice if you can't and save it on a floppy. Take it, along with all other relevant documents to your local police station and inform the officer at the desk that you want to lodge a report. Give his a brief summary of what happened and pass him the disk. This is where it'll come in handy as most cops aren't really proficient at typing. You may or may not be referred to the fraud prevention unit which is in Dang Wangi (provided that you're in KL) so be nice to the cops lest they give you the run around.
