Just as an FYI to anyone who may find this thread in the future, Bang CD (or "Apex Champ Ltd" as they are also known) are in my 'bargepole' category now. Having bought several items successfully from them, in late 2009 I attempted to order a blu ray disc set. I was told via confirmation email it would ship within days, however it didn't. Customer care were incommunicado on the issue. It never showed up, and no enquiries were responded to. 5 months later their 'customer care' contacted me to tell me the item was not available (it is available elsewhere online and on the street, it is not an unusual or rare item), and that I'd be getting a refund. That was a relief - except of course the refund was never issued. And again, any communications to them were ignored.
I have just been told by the European Consumer Centre (Ireland) that 'obtaining redress is unlikely', as they are in Singapore and there's little that can be done. Due to the length of time that has passed and the relatively small amount of money involved I'll leave it there and will not pursue via credit card company etc..but lesson learned. I haven't really strayed from Amazon since.
