Alright I'll try to contact them again. Though I've sent them an email each week till now so I'm pretty sure they have received my email. Also, I forgot to tell you this but last week I received a short message from them asking me if my E10 had a "gold jack" and a word "Olympus" written on the E10 and the packaging. From what I can tell, they are going to tell me to get a refund and buy the latest batch. I don't think they are going to give me any solutions to fix my current E10.
As for the seller, I think they are an authorized dealer. I saw their product on ebay and bought it from there.
Here is the link to the product: http://www.ebay.com/itm/FiiO-E10-USB-DAC-Digital-to-Analog-Signal-Portable-Headphone-Amplifier-Amp-/290795477514?pt=LH_DefaultDomain_0&hash=item43b4c2da0a
And here is the link to their site: http://www.sonicelectronix.com/
I live in Australia and at that time, when I checked my local and all around Australia to find a seller for E10, I couldn't find anyone thus I decided to buy it from Ebay (which turns out that seller is currently at US). I think my first mistake was here: I've just found out that on FiiO's official website they link to the stores which they supply and when I checked Oceanic there were literally 3 or 4 stores available for Australia (all of them have the latest batches from FiiO).
But yeah... what's happened is happened, I can't change the fact that I didn't do the research enough. But that doesn't mean sonicelectronix can send defective itemsTWICE in a row and not responding to my email... and also telling me to sell the item on Ebay and buy it somewhere else... what kind of customer service is that?
I don't know what to do anymore. I might go buy a new one from one the stores in Australia but that just means that I have wasted nearly $100 on my current defective DAC plus shipping charges.
