Software Empire Bogus activation key. Software will not install. Unable to contact. Clearwater Florida

I purchased MS Office 2016 from Software Empire in June, 2017. I downloaded the software and followed instructions given in the email from them. I entered the activation key to complete the install but I got an error message that the key was for another program and the installation failed. I attempted this install with the key several times but it never worked. 

I tried calling several times and left several messages for support to help me out but they never answer the phone and never call back. I dusputed this to my bank and they refunded me the money and proceeded to investigate. Software Empire answered my bank and said that I already downloaded the software so the bank just took the money out of my account again. I opened another duspute because I cannot use the software. It doesn't matter if I downloaded it or not, the key is bogus and I'm unable to reach Software Empire. They don't even have a web site anymore. DO NOT BUY ANYTHING FROM THEM!
