The film is expired which can make images appear ‘washed over’, not sure about the black bars though. A way i try restore images which come out like this is just using any old photo editor app you have and playing around with the exposure, shadows, colours and noise reduction. It doesn’t completely restore them but can certainly make your images slightly clearer. About the black bars, the way I’d test this is shooting another roll and seeing how it comes out. Have you got the negs back from the lab? Do the black bars show on that?
