Did u buy the gear box eyes closed or did u get it delivered to ur door step?
Im sorry i havent seen a transmision ever before in my life so im not realy sure, but there should be something written on it, maybe atleast the model.
Any one i have dealt with in shairshah, my experiences have been gud, even on returning things that became extra for me they have no issues.
One guy was son of a gun, whom i called asking about the mirror on the fone the guy said its avalible for 2500 only, when i went there with my father the guy asked rs.4000, that too hee didnt had the mirror, and most of all the guy refused to had talked to me, i even showed him i called him and call duration. at first he said im in namaz at the time u called, then i said whys the call duration then did i talk to ur ghost, the guy had nuthing to say.
My father said its just there tactics to trap customers and then rip them off.
