I am now also one of the suckers that bought a phone from DHgate which does not work and I lost my $144.99 USD. After about 20 emails back and forth with the top seller Cecelia and my promise to send it back prepaid the seller gave me no return address. I send all the required info to DHgate 1 day prior (my time) before the closing date to mediate but they had send the money already on to the seller. After numerous emails to DHgate to get my money back with no result I gave up. So be aware to deal with DHgate and don't get caught like I did.
I have bought some items from Alibaba since this fiasco with DHgate, with excellent result.
