Look at the following link for the LG Blueray drive (Retail) for sale on ebuyer and check out the reviews. You will see that the supplied software needs to be upgraded at cost to enable playback of Blueray discs - is this the same complaint to which you are referring as from your initial post it appears you did recieve Cyberlink software just that it wasn't a version that allowed B/R playback. If I am correct in my assumption then Mesh haven't been at fault in charging you for the upgraded software.
I think you have to be a bit carefull when quoting "fit for the purpose". The problem is not that the drive won't play Blueray but that at the time of purchase you were not offered the software upgrade to enable full Blueray playback. This does not make the drive unfit for the purpose and can/has been easily rectified.
Also click on the link for the Mesh order site and you will see if you scroll down to "additional Software" the option to select and pay extra for the Cyberlink Bluray software is offered for £29.
