Just received an email saying that my dispatch has been moved from 17th - 20th to on or before 24th Nov due to them 'currently experiencing delays in dispatching the order'
Thats not too bad then. Assuming mine says on or before 25th as it was a day later than yours then its only a couple of working days later than the end of the original window.
Doesn't help when you want it right now though lol
