Rant alert.
Left negative feedback for some printer cartridges, although I admit I didn't contact supplier beforehand (just finally had enough of a whole month of intermittently rubbish printing). Next thing I know supplier has phoned me and emailed me to say that it's 'not legal' to leave negative feedback
and that I should remove it!
Have phoned Amazon who say this is not true. Meanwhile supplier has emailed again to say that in order to get correct print quality I need to 'up my print quality in my printer settings'. This means documents now print at half speed and presumably use twice as much ink.
