Definitely lost. It usually is, especially when they pull out the "Account Hacked" response.
Don't keep your hopes up for a refund as they'll just chalk up the incident as "User Negligence" and that's it.
Unless of course, you can somehow prove, the leak wasn't from your end. (Quite impossible to prove)
I'm quite curious, before 2016-10-28, when was the last time you accessed your account there?
If it was 2 years back, then it's quite a pity that the said "Hack" happened not even a month before you finally logged in.
"They" probably thought it was a forgotten account or something.
Anyway, sorry for your loss.
After urging them to give me my money back,
they have acknowledged that their site had been attacked (so it is not a negligence from me), but they definitely refuse to give the money back.
Here is their answer:
"Hi,Very sorry,Hackers have been turned away.We can't return it to you."
I will keep you posted to see if they do something. In the meantime, bter.com must be considered as a farce, and should be avoided at all costs.
