...I left my number up. Not one phone call. I'm free after 415 pm eastern
Of course you didn't. The discussion is here, on this forum, in this thread, not on your phone. Sorry, but that is just the way that forum discussions work. If you want folks to know your side of things (and comments like "I have a right to be just as angry" are meaningless without context) then you need to post your thoughts here.
At this point you aren't looking too good and anyone doing a search on your business is going to find this thread. If I were in your shoes, I would certainly give my side of the story here. Expecting people to call you is honestly unrealistic and even if they did, won't undo the damage being done in this thread. Your call, of course, but the fact that you are failing to respond isn't helping you any. A solid response, logical and void of any BS, would go a long way toward getting people to see that there are indeed 2 sides.
Being "hit hard by the economy and medical issues" is an excuse for individuals, friends and family, but not for anyone who has a business and takes someone's money. If you look through this forum you will find innumerable instances where people have deals-gone-bad because the seller uses this same excuse. Typically, it turns out not to be true (not saying yours is not true - just that this is a very, very common false excuse). Sorry, but none of that is a valid reason for not handling this guy's issue properly by returning his money.
All that said,
"All is being refunded. All communication on my end from this can be directed by email from buyer. I'm fixing it." is great to hear. Hopefully, it all works out for the OP. He seems reasonable in wanting to get back only what he put into this situation. That is fair - reading only his side of the issue.
