Will have been a cat c due to the inside panel being slightly damaged, a new bumper, taillight, painting + fitting would be in excess of £400 from a body shop, never mind a rear panel.
They would probably want to fit a new bumper which will be hard to get hold off now and the claim also takes into account how long you may need a hire car etc!
