Purchased Microsoft Office Home and Business 2013 in November 22, 2013. I received an email with product key and link to download the program. I request assistance in installing the program because I had trouble downloading the program. I got another email with different link. This time it worked but the program was Microsoft Office Professional Plus 2013. I noticed the product key was a counterfeit when I had trouble reinstalling the program after my laptop was serviced. Microsoft told me that the product key I had was used over 13 times... I tried contacting the Ace Technology Online but no avail. I contact paypal but because it was past 45 days, they couldn't do anything but deal with Seller directly. I have been reporting to Microsoft in numerous occasions, but I am not getting anywhere.
