Very unsatisfied

I collected a car... Before all somethings where missing from the outside. Also inside. Day two of driving there is wind and water getting inside. I also learned that a rubber was removed on the door. My key is not even working now.

I took my car in for a bumper and passenger fender.. How does a rear door rubber get removed.

Please fix my
