Hero Motocorp — fifth free service non availability of indicator switch

Yesterday i went for 5th free service to venad automobiles vendermukku at kollam, kerala for my glamour two wheeler. They made the invoice at 1610 hrs. They told everything is ok. After delivery i just travelled about 300 meters and i found that the indicators are not working. I came again the same moment told about the complaint, they have done something and told its ok. Again i travelled for few meter and found that the indicators are not working. I came back and handed over to them. Finally they handed overto me my bike at1730 hrs and told me that the problem could not be rectified because the indicator switch is having some complaint and it is out of stock.
