I typically refund anyone that would email me saying they cancelled a day too late, or anything of that nature. And, I always respond to EVERY email I get; however, sometimes people that have lame email addresses get thrown into the yahoo 'junk' folder and I never see it.
So, long-story-short, if you don't get a response back from me on email, it means that I didn't get it. And, you should either send it again, or send it from another email address. Any time you do ANY business that involves ANYTHING important -- you should always use a 'paid for' email address rather than types that often get flagged as spam by ISPs.
And, to clarify, I don't recall ever getting any email about this situation. Of course, I get a ton of email every day and no one gives their forum names..and half the time they don't give ANY info ...so it's hard to match them to people here. But, if you didn't hear back from me, it either means I didn't hear from you or my response didn't go through.
Oh ..I do remember getting an email last week about something and I responded and the email didn't go through (bounced back saying it was invalid.) Seriously ...why would people email me using bogus/spam email addresses? Use your REAL email address when you contact me...
