Address:

F-54, Ambalal park society, near poonam complex, waghodia road, vadodara 390019, Vadodara, Gujarat, 390019

I have brought hero glamour fi on 12th september 2019 from kumar motors (Address: khaswadi rd, behind aradhna cinema, salatwada, karelibagh, vadodara, gujarat 390001). But it is not working properly. I have complained in kumar motors but they told me to submit my new bike in their workshop. They will check the problem and will solve. I have submitted my bike for two times in workshop but still i am getting the issue. I told them to replace same bike but they told me that they don't have access to replace it. I am helpless. Please help me.
