You should be wary of any company that doesn't include a customer services phone number on their website.
My fiancée ordered a wedding dress from Hebeos. It arrived creased, having been carelessly shoved inside-out into a bag, and it looked nothing like the picture. The materials were of a very poor quality and the fit was terrible. The dress was clearly several sizes too big.
When we complained (by email, since there was no other option), we were told to take the dress to a tailor and offered a 25% discount. There was no way we were going to keep this dress, so we complained further and they increased the discount to 40% - despite our insistence that we DID NOT want to keep the dress.
The emails from Hebeos were brusque and whoever wrote them clearly hadn't paid any attention to our complaints.
This went on for some time. We threatened legal action several times, which they ignored. Eventually, they sent us some return instructions, and we had to pay £30 or so to send the dress back to CHINA. A month or so later, we finally got a refund.
