not happy at all, almost 30 years with you, a month ago I am on a street, I just passed a speed reducer, I put my flashing light, I start to turn in the street on the left, a little youngster with a 50 cc motorcycle which strikes me in the back left because it was starting to double at that time. it was not injured but shocked the poor. a month after no news, I called maif, who told me how wrong i am !! I had to be careful because it was me who changed direction and he had the right to double, the youngster was behind, sees my flashing and double anyway !! I do not understand everything. a gentleman even stopped to tell me that it was the young man who was at fault and that I had put my flashing light, the young man himself apologized and recognized that it was was really his fault, well finally, I do not intend to stop there, I have qd even 200 euros for repair. is there a recourse / complaint to make? member for 30 years at almost 500 per year, thank you m a i f, I will find out from other insurers if someone can advise me, thank you in advance.
