In a nut shell, they denied my rebate claiming I did not mail in the invoice for the product. They claim that I mailed in the sales receipt instead. I know what I mailed in and I have copies of everything. They responded to my email and said it was declined for that reason and then cut off communication. I emailed several times and they did not respond until I filed a report with the BBB.
They then sent me what a sample invoice looks like in case I did not know. So I replied and sent them my invoice. They responded and said that they have a resubmission policy of 14 days from the date of purchase. Which is absurd since i know that they did not deny it within those first 14 days of me mailing it.
I never received any correspondence saying it was denied and they refuse to discuss the matter further. They offer rebates on many sites, I purchased on newegg. But they all have a site they sell computer parts on, eaglebit.com. I would avoid their site and products. A simple google search will reveal that they do this to many many people.
