I understand your frustration. I try to always be understanding. Computer may have crashed, phone lines down, family emergency, or just a glitch in the system that didn't get the email delivered one direction or the other.
I had a request one time and before I could get back to them with information, my computer crashed and I lost contact. I hope they don't think too badly of me.
Someone recently emailed me about an ad I placed and asked for a TON of pictures, which I sent. Never heard another word from them. I hope those pictures got through. I think they were in Texas.
If you have emailed me, and didn't get a reply, please try again.
