I've made a second deposit 2 days ago, but probably I forgot to press 'confirm' at the site (I don't remember). The amount never showed up under my balance. I sent a ticket two times, got no response.
This might be a dumb question, but did you check in the support ticket on the site? The first time I sent a support request, I was expecting an email reply, but actually got one on the site within the support ticket. Just thought I'd mention it...
