Yes, can they please get the right people to attend our cars instead of damaging the

I Brought my Opel Corsa for service two months back, it was on 90case and after wards the engine light keeps popping up every single day in the morning and I've been bringing my car but they can't resolve this matter and it's affecting my work now because I always arrive late for work, I'm getting a *** service here because they can't fix the ****** damn thing..... If they don't have the right people to fix this issue I'm experiencing they should just tell me and I will take my car to another dealership I am so angry ???? ???? ???? ????
