I have given my honda activa for servicing in jsp honda service centre, oragadam, ambattur, chennai 62 on 12th feb 2018. At that time they told total cost will be 1500 for servicing. I told ok nd went on 14 th and they handed over me the bike, i checked and found nothing servicing done just cleaned top layer nd given but costs 1800. I kept my helmet in bike, someone taken nd they r not responding for that. This us the worst service centre i have seen. Pls atleast handover my helmet to me
