Did you make an attempt to contact them?
I don't really see what difference that would make, since the onus should be on the retailer to provide service, and not on me to chase it.
But since you have asked, yes, I emailed them to ask why the order had been canceled, I got an automated reply acknowledging my email, but I didn't receive a proper reply, let alone an explanation of why my order was canceled. At that point I thought well if they can't be bothered neither can I.
I was not going to phone them in Hong Kong as I was not that desperate to buy from them particularly.
I am aware that there can be all sorts of reasons why there might be problems with communication etc, and I will make allowances for that, but at the end of the day I am the customer and so if a retailer wants my money then they have to put in some effort too and not just expect me to chase after them to sort things out.
I am not one to chase a retailer if they do not reply to my emails, there are way to many on line retailers to have to bother with ones who can't even attempt to reply to an email. I just bought elsewhere, and won't shop with JK Army again.
