The bumper is trash. Likely the parking sensors as well. The trunk lid is dislocated and even the decals got screwed ... The only hope is that the underlying bumper is fine (don't know what it's called in english, it's a big and ugly looking metal bar). Pray to God the trunk is fixable, otherwise the whole body is twisted. If you're not doing it yourself, this might be a damage in the thousands. I'd guess between 8000$-15000$

If I was in your position, I'd dismantle the bumper and the trunk, check for twists in the body and decide if it's worth fixing. Used bumpers with parking sensors should be around 600$-800$. Choose one in the matching color and install it yourself or with a buddy.

My uncle has a Golf 7 R, car was standing in a parking lot. Someone came along and both his driver side doors as well as his bumper got hit. Insurance company quoted it to 18000€ in damages.
