Scumbag DVD online renting company (based in Perth), hit me up for a membership I had NEVER applied for. Disputed it with the bank, got the $30 back. How they got my credit card is beyond me, and I even received 3 DVD's in the post (which I posted back same day, with messages inside about wrong details etc - no, the video's were not worth watching either
)
They tried hitting me AGAIN, and this time I sent them a rather legal letter. They ceased immediately.
Again, HOW they managed to get my credit card number is a mystery, as I KNOW my wife did not do it either.
