Extremly slow service.
I have ordered a few times missing parts from sets. When my children were younger, they did not take so good care of their Lego and now that they are older, they'd like to rebuild there sets.
I'm really happy that you can buy almost all the missing parts from Lego and that, including the delivery, it's really cheap. So that's a great service.
However, before Corona it took almost 2 weeks for them to send the parts and another 2 weeks until they finally arrived. Which was quiet a long time already.
Now it was a whole month before they finally send my missing parts. No idea when they will show up, it's been 4 days since they were sent, so I guess another 10.
When you order from any other online shop, it takes 3-5 days maximum for your parcel to be shipped, I don't understand why a company like LEGO needs a month
