Apparently the 23rd Jan date was a complete fabrication, their supply system makes random guesses as to when parts will arrive. We’ve now been assured that it’s all the fault of the Germans, the parts are due in this week, and that my laptop is at the top of the pile to be repaired when the parts actually arrive. In addition, if the parts don’t arrive this week they’ll cannibalise a new laptop to fix mine, and presumably others as well.
The cynic in me believes this is just a ploy to shut us up for a few days, but we’ll just have to wait and see. It does mean that it could be at least another week before my laptop returns.
