Workshop order and non-order repair – what to do?!?

Hello guys, have written in various other threads of my flap front right… Now the car was in the workshop, with the order to remove this flap or to find the reason for it. The workshop had now found the reason for the flap and changed the trouser tube of the exhaust system… Only the flap is still stupidly still there and is getting worse… Can I do something legally?!? Especially because the somewhat plump statement “…the trouser tube was broken anyway..” came from the Audiman this morning in the workshop and this has behaved quite unculantly… I also don’t go to the doctor when I have a headache and let me prescribe something for my stomach, because the doctor has “fixed” this by the way and I don’t notice anything about it… Did anyone ever have such experiences?!? MfG Bastian
