When Ngzhang started to sell his Batch #3 in China, a Chinese buyer want to visit him and sign a contract on paper. However, Ngzhang refused. They hide their ass, refuse to communicate and respond. I think that's why the buyer started to look for their parents. Their parents may have the access to contact them.
I can understand frustration, but going after someone's parents in order to track down someone seems well over the line. I'd prefer that people who make promises either deliver or explain why they can't in a meaningful time frame and to the satisfaction of their customers. Warning signs that he wouldn't sign anything right? Guess we have take serious notes on that and the current inability to communicate and shop elsewhere. Makes perfect sense not to trust these people ever again. The only way at this point to change that opinion is to change their pattern and communicate effectively and provide refunds immediately to all that ask. Let us see how they resolve the remaining issues. There is some positive progress but until there is a complete resolution to all grievances this company can not be trusted.
