I have a camera and two lenses on order with D-D photograhics in Sydney, been waiting a month. Checked the website today and there is a banner claiming they are under new ownership. A google search reveals they are refusing to honour outstanding sales.
I'll contact my bank on Monday and request a chargeback.
I would have thought that if you purchase a business then you are also purchasing their sales contracts. Not sure how they can legally claim to not be responsible for outstanding contracts. If they are continuing to trade and still using the original website then that should amount to fraud.
Caveat Emptor!

Crossing my fingers the bank can get my money back.
