i just bought these awesome DVDs at Yesiasia.com by credit card ( i'm using ,mastercard btw)but after they confirmed the purchase, they sent me the letter saying that they cannot verified my address but i'm sure that i got it right then after that, they keep asking me for a copy of my front and back of my credit card(i can black out the middle digits on the credit card) or a copy of my credit card bill
basically , they just want to verified my adress but my mum keep saying that they can make fake credit card out of the copy ( and it's true

) and so i keep hesistaing whether to just copy the things they needed or cancel it and make a new order . i'm living in autralia btw. the only solution i got why they can't verified my address because i'm living in a granny flat now and i wrote (UGRFL < not sure how i wrote i but somthing like that) on the address i gave them and since they're like asian (no offence

) i think their system can't recognise it and yeah, that's my only solution
Can anyone help me with this? Should i give the the copy or cancel or something else?
is it trusworthy?
VERY VERY VERY VERY SORRY FOR THE LONG BLABBERING PLEASE HELP
