Honda Dio — Self start not working within 3 months

Address:

Honda show room, padi, Chennai, Tamilnadu

Dio bought on September. Self start was not working and gave it to the Service center for repairing it. It took 2 days. When they gave the bike for delivery. I was shocked to see the self start switch was replaced with old one. When he tried to start it was not working. After 1 hour of checking again they say that the battery has gone and want to replace a new one. After leaving the bike there for 2 days. They have replaced a old switch and didn't check the battery as this should be checked first. Such a worst service
