Tom, it's sad to see you're still giving him the benefit of the doubt after all his excuses, sometimes I wonder if you're his Schill. I've never seen the Post Office "Lose" so many packages from one Vendor. If and when they were finally "delivered" to the P.O., the Tracking Number, if you received a valid one, never updated. The other excuses were always about the "Finish not being right", or "it just needs the electronics installed."
I was one of the lucky few, two Custom DNA 20's ordered the end of April 2012, never bothered him, shipping notification ~6/24 with a "Tracking Number" that wasn't recognized by USPS. My first two contacts were after the 4th of July Holiday since my package hadn't arrived, I got the "bad finish excuse", and finally 10 days later both boxes arrived without notice.
They both look beautiful and work splendidly... I hardly use them because of Marcus' total disrespect towards those who've purchased his products in good faith, and deserve a response regardless of how long they've been waiting. If he has time to delete messages from his Face Book, and continue taking orders, than his current clients should be as important as his future clients. If he's so "backed up" quit FBing and taking new orders until you're satisfying your current clients, "word of mouth is a powerful advertisement", positively or negatively, it's his choice expressed by his actions.
As for the number of negative posts you've seen... does the number matter more than the length of time it takes to reply to a simple request, or or how long any complaint is successfully rectified. Poor Customer Service is poor Customer Service, and you can receive it from nice guys as well as egg-heads, to put it nicely.
The bottom line is, when someone is looking for a good product, they'll also need great follow-up for any future problems, do you really think they can count on that? I sure don't!
