I've bought 15 mhs of Zen. Makes a decent return but I got pissed off because every time, without exception, the withdrawal of BTC does not work until multiple attempts are made. I asked for my money back and they told me to fuck off. Well I am still within the window of my credit card purchase and can tell them to fuck off and there is not a damn thing that they can do. It was only $350 CDN so I may just ride it out to get my ROI as I do get my BTC eventually.
Maybe you should be more patient? Because I heard they are working on smoothing things out now and whole customer service will be a lot better. So why you want to resign when the ROI is really good? Armor yourself with little patience and have some faith. GAW will deliver, they always do.
