Emails too easy to ignore in the hope they go away. Ring them up and ask to speak to someone regarding the matter.
I'm actually pleased to be able to go around them to Amazon... previously Amazon took a couple of days and then found in my favour, problem solved. I think it's less likely here... a full refund would be unfair on the company, but I'll see what Amazon do - I would imagine the company would be unlikely to ignore an Amazon email.
