@drstevo. I placed two further orders after this and have received both a week or so ago. I think this one is well and truly lost. I want my money back so I can order them (drippers) again because I still want them.
I was under the impression that the deadline for opening a dispute was 45 days but once you've done so, a new timetable comes into effect. Or am I having one of my 'moments'?
