On 7 September 2017 I purchased a copy of Office 2010 from this site. The software was sent immediately by email. The license code was invalid. On 13 September 2017 at 1221 hours I was able to chat online with "Mark" who provided a new lecense code by email. This license code is also invalid.
Since then I have been unable to contact them by email, chat or phone. The address on their website: 3509 Connecticut Avenue NW, Washington, DC 20008 resolves to Opus Washington Virtual Offices.
