Just seeing the end of the road on this saga and I’m posting a further update.
Like @Jimmybob (Mark) my consignment was three and not the six I ordered, despite the invoice stating that 6 were sent (and 6 was the tally for HMRC to levy)
By now being fairly cheesed off about this - effectively I’d paid nearly £60 per bottle; the most “valuable” being the O.Schell Quattro Cuvée https://weingutschell.de/produkt/quattro-cuvee-barrique-trocken/ a barrique-aged spatburgunder which retails from their website at €19.90. The other two, like Mark’s, were an entry level pinot and riesling - I expressed my frustration to the flutwein people and they have offered me a complimentary fresh mixed 6, and luckily I have a French post-restante address to which it will be sent this week.
I will also complete form BOR286 https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/978896/BOR286_-_English.pdf to claw-back most of the tax and duty I was charged for.
So, @Jimmybob , and anyone else still left short-changed from this debacle please contact Daniel Koller email@example.com and try and sort something out with him. I am prepared for any of you who needs it, to supply you my French address to have it sent to, and I will bring it back to the UK late September and post it to you from the UK.
I also have his phone number and so message me privately for that if that helps.
