Accident Gants Hill Roundabout in East London !! Need Help :(

I have a really bad experience today . Very trick roundabout in Gants hill. On Traffic light i was taken position in the middle to take exit to A123(N) . Once green shop up all vehicles tarts to move. I moved in to 2nd line from the left and lady from the right line move into 3rd line and than she wants to take exit in to A1400 which is basically 1st exit from after traffic light and mine is 2nd exit after traffic light. Apparently when i start to move after couple of seconds she crashed in to my car right side of the car ( back passenger side ) When i come out from the card she was telling me that her husband tell her that i have to give her a way... Which is looks very funny... When somebody give a way on th movement.... No i dont know what to do and who fault is that. I meet up with my friend and he is saying that it is her fault because she can drive in to the car she needs to way until all the cars is pass and if she takes wrong lane than its her problem.
