Very disappointing service

Such an underground service I have ever experienced. A spring was not included, which was objected to by me by mail. They then asked me to take a photo !! ??? From a lack of spring ??? Of course I made a photo. One spring I have not to this day.
In addition, the building instructions appalling: Dark black and white photos of the very poor description is comprehensible at all. It is mentioned with no word as exactly the elastics on the blue cover are to be fixed, after the first demolition, we chose not to fix this. A clamp for securing the mesh bars was not to assemble. Since here also came to demand a replacement, I have increased the diameter by filing.
Then maybe Hudora .....
