Brancott Estate Sauvignon Blanc Marlborough 2019 6 X 75cl

I am not a wine buff by any stretch but this was in over in my local supermarket for a while and I really liked the 2019 one. When my local supermarket started stocking the 2020 it didn't taste as good, and neither did the 2021. Which is why when I saw this, advertised as 6 bottles of 2019, I ordered immediately. Unfortunately they sent me 2 bottles of 2019 and 4 of 2021. I will still drink it as it's broadly fine, but I am a bit annoyed as it was sold as 6 x 2019.
