webuycars, dekra report false information

I recently got bought a car on auction , the dekra report showed engine :very good,and engine noise: very good. I expected the car to be in a good condition after inspection from multiple mechnics the rings is gone and timing chain is gone,and the engine basically need to be redone after i reported it to them they said nothing can be done, the dekra report is so that you can trust what they say is wrong, its a lie and inacurrate.
