Is there anyone bought some items from Rainer? I sent a wire transfer to him as payment for this Cube. He then replied that his assistant sold the cube to another buyer and he did not know about it. I asked him to return me the payment. He said that he did so. However, when I asked for a wire transfer document, he have never sent me anything. I have waited for about a month and no money has been transferred back to my account. I tried to send him several emails to check this issue. Only some short messages have been replied such as "I will check for it" and then he disappeared. Not sure if any other buyers have the same problem.
