It may be a complicated case, but you can still change solicitors. I did with a car crash years ago. Ive always used RMNJ in Birkenhead, but because my passenger had already put their case into Kirwens in prenton decided to go there to keep all in house. What a waste of time they were. No feedback, no updates, it was a simple whiplash case (yes, genuine, still suffer now, 20yrs later!) and they took over 18 months before i had enuf and went to RMNJ and asked them to take over.
Even then i had calls off Kirwens asking me why i changed solicitors...which they arnt allowed to do!!
IF IT HAS A HOSE THEN IM YOUR MAN
BETTER TO BURN OUT THAN FADE AWAY!
