Honda Cars India Ltd. — Mileage issue of my honda car and worst service of Harmony honda mohali

Address:

Mohali, Punjab, 140301

Hi,

I am facing mileage issue of my honda amaze 2014 (Pb-65-y-7225) june model car. From last 1.4 year i am complaining about the mileage issue and 1 time they have asked to hand over the car to harmony honda mechanic and they will check, upon returning they told that in our machine it is showing mileage of 20kmpl but they never showed me where it reflects 20kmpl. After that also i faced mileage issue and it came down to 17kmpl, after that harmony honda told that you need to replace air filter and the same i did 3 week back, but still the issue persist and now with ac in city, it is giving mileage of 15.8 to 16kmpl.
My question is that are harmony honda mohali engineer well equipped enough to understand the problem because they only focus about closing the issue rather than actually solving the problem. Even honda customer care is not sincere in helping us, they just route it to the honda dealer and never call the customer to ask as whether the issue has been resolved or not and the same thing with harmony honda as one of the worst ever customer service.
