I keep seeing "I hear you", but I'm not sure you understand.
The fact that you would still not be able to provide a concrete delivery date after 3 years is a problem. That's the real issue here.
There was a point in time that I had specifically come out in support of you and posted that you should simply state you need more time due to personal issues, rather than keep making delivery promises that would be unfulfilled. Everyone would have understood that and respected the honesty and consideration. But you didn't change a thing. For all practical purposes, you ignored the lifeline that was thrown out for you and kept on with the cycle of promising, missing, excuse, and ghosting. Speaking only for myself, the fact that we are here now, and you still don't know when you might deliver is outrageous.
Look, as far as any personal issues you must deal with, I continue to wish you only the best and hope that everything works out well. I'm very sorry to hear that you're still dealing with difficult challenges in your life and I hope you come through this better for the wear. That said, if you're not going to effectively communicate, and if you can't deliver to your customers in a timely manner, or you don't know when you might deliver, then you probably shouldn't be offering anything for sale. Apologies if that seems rather harsh, but the reality is that your reputation has suffered because of this and there are a many people that will never order anything from you again. Just to put this in perspective, in less time than it has taken for the Joker Hands and the Dent Shoes to materialize (which is still on-going), I, along with several hundred others, have already received a 1966 batmobile that was designed from scratch and licensed by WB and already delivered.
I've seen some of your dark knight stuff and one of the words that comes to mind is "genius", - but I wouldn't order it from you just because I refuse to go through this type of ordeal anymore.
I have no doubt that you would prefer not to be in this situations, and I feel for you, but again, you had complete control over this. Until you get some type of consistent delivery and communications method, this type of stress will continue, and that's no fun for anyone.
