Hello, just joined the forums. (well been lurking here for a while) Would like to say hello to everyone

Hi I recently had a car accident where I was driving in the middle lane of a 3 lane roundabout, and there was a car in the inside lane that swerved out infront of me without indicating and he went straight into the outside lane, Due to this I quite sharply braked and managed to avoid hitting him but the person behind me did not break and hit me from behind, The situation was all amicable between me and the other driver that hit me, we exchanged details etc and made sure no one was hurt, she admitted she should have reacted quicker and it was her fault etc. The problem I am is with the insurance company, basically I'm with admiral and they assigned the case to Albany Assistance, which sorted me out with a hire car, and sent my car to a garage to check the condition etc, Eventually after many phonecalls they advised me that the case is referred back to Admiral and that my car is a total loss and they valued it at £790. I got a call from Admiral and they said the same thing, but I am absolutly furious that they valued it so low, I brought it originally 2 years ago for about 2k and it's in very good condition for what it is. I asked why they were dealing with it and not the 3rd parties insurance company and they said they were going to initially settle it with me and claim the costs of the 3rd party themselves, I tried to negotiate a more reasonable price but the said that this price was non negotiable. I don't know what to do now, I've still got the hire car but the price they've offered me is ridiculous, I'm not trying to be money hungry or anything, I just want the price my car's worth which is about £1300 - £1400 Could anyone advise me on what to do next? They've so far put my claim on "Hold" until I decide what to do but they haven't given me any other options lol. Also is this normal practice of my insurance company settling with me then claiming there costs from the 3rd parties insurance company which is LV. Any help would be great. Also thanks for taking the time to read through this.
