Questions about Samsung WD80T4049CE/WS WD4000

Is the depth really 72.5cm? Our current machine is 20cm less and I see that so are many others. Wanted to check this is not a mistake because seems quite a huge difference given other features are the same as out current machine...

Please, it is possible to select a delivery date ? E.g. on saturday ? Thank you.

I see that in the user manual of this machine, depending on the model (not indicated in the manual), there can be two water inlets (hot and cold). Can you confirm if this machine has only one cold water inlet?

Is the cold water connection 3/4 inch (standard in Switzerland) or e.g. 1/2 as in Germany?

I don't understand why you have to select 'delivery and commissioning' and then additionally the service provider (e.g. Cool AG) - then the costs would be 126.- plus 184.- = 310.- ?

Are connection hoses (inlet and outlet) supplied?

According to the description, this product is in energy efficiency class A+++. But on the SAMSUNG website, the best washer-dryer is in energy efficiency class A. There is no appliance in the A+++ class. I guess it can't be that this is an old model and the newer ones are worse. So the information is not correct? Or are there different classifications? Maybe the classification has changed? Can you help me?
