Twice over the registration information sent to me for the Microsoft Office 2019 Pro programme which I ordered were not legitimate product key codes and therefore that which I purchased could not be activated? AS time was not on my side, out of desperation and in an absolute dilemma I downloaded Open Office Apache 4 in order to be able to carry on working on my PC. It would appear and this according to Microsoft that CJS Keys are not issuing individuals with legitimate Product Activation codes and therefore this company cannot be relied upon where purchases of this nature are concerned! As MS Office 2019 Pro is a downloadable product direct from Microsoft's own servers no Courier or postal services are in any way implicated in obtaining this product?
