Gutted for you mate, same happened to me a week before christmas but the f**ker drove off to leave me to come back with the paint taken off my rear bumper
Yours is worse due to it needing to be re wrapped. If she has admitted fault i would wait for her insurance company to call you, no need for you to inform yours. This was the case a few years back when i got rear ended. Their insurance ended up doing a straight forward bank transfer.
