Communication and Dekra Report

I bought a car on auction and the problem started with the lack of communication by the sales rep delays in delivery. I finally got the car delivered however the dekra report and what I received were 2 different things. Needless to say the filth and also that the car has burnt interior only notice when the valet is and under the roof ceilings. Theo is the salesperson. I don't know why they neglected to mention as this was an online auction and the burnt marks are visible
