Bought Office 2019 key from these, was told to install via phone method rather than activate online, tried this and it failed, was then told to call up Microsoft directly, did this and was told by Microsoft representative that the key was counterfeit. Went on PayPal to start a dispute and was greeted with all sorts of warnings from CJs CD Keys advising people not to start a dispute. Have since bought a legitimate copy of Office direct from Microsoft anyway as this seems to be the only safe way to get one - I have had previous purchases from CJs and they've usually been alright so was really disappointed with this as it seems they've switched their key supplier which is a real shame. Won't be buying anything in future from them.
