I saw this thread and thought "Oh cool.... I'll give it a try". I had this half of an LTC (What ELSE ya gunna do with it?) and so sent it to this Zino site, having registered. It didn't show up.
I looked around the site a little closer and evidently they have this 'minimum deposit' thing of ten bucks. That seems sort of stupid to me... why have such a thing in place with virtual currency...? But it's their thing, whatever. So I wrote them and explained what happened and asked what to do about it. Never heard back.
Sure, I could deposit some BTC to bring it upto ten dollars (WTF, by the way, with this registering of everything in USD...? That feels a little greasey to me), but ... ehn, with that sort of level of (failing to) responding to customer questions, heck with it is my attitude. Sure, you soaked me for a couple bucks, but I don't think I will be back. So that's all you're gunna get.
Edit: They did, as of today, (Sept 2) respond and credit the account. So gripe dismissed.
