dont know where to put my question so i'll ask here.

couple of days ago i accidentally broke my friend's iswara turn signal(terkena lutut dont know how i did it).so now it can't signal to turn.and it keeps flashing left signal whatever i do and it wont stop.
so i went to a nearby workshop and they told me it will cost me near RM100 to fix the turn signal.the mechanic said he need to order a spare part as the turn signal is broken and cant be repaired. today the tauke said no got spare part anymore and to order a new one he needs rm1000 wtf.he's saying that because it is too difficult to get that particular spare part.he's trying to find other spare part now i dont know what he's talking about going to a half-cut workshop to get the parts.so i would greatly appreciate if anyone can help me here.does a turn signal cost +-RM100?
