It can defo be repaired, it's what I do as a career. If you google "smart repairs" or "textured plastic repairs" you should get someone in your area to help, but check that they can do black plastic repair as opposed to painted/sprayed.
I would charge approx £50 as it can easily be removed.
The process is straight forward if you have the tools and of course the products etc, it's not really a job you can do without if you want an invisible repair.
Hope this helps.
