Not as best as expected.... Review on Honda Dio

I have bought this honda dio to gift it to my sister which looks pretty cool and amazing and apart from that this scooty has got highest rating in which honda company ever made after activa and that topic interests me it has also got the excellent mileage and good comfort with pretty looks which is best suitable for the girls.

But after two servicing the showroom manager said that it should get 60km mileage in the cities but I am not even getting atleast 40 mileage so I am very dissapointed with the scooty and I complained about that and they said that they will analyze the problem and they will recify it. one thing is for sure honda company has got the good service on the very next day they came and inspected the vehicle and they took back to their service center and after next day they returned and said that it will go now atleast above 50 km per litre so the mileage of the scooty is satisfied and the good service of honda.
