Honda 2 Wheelers India — after service complaint is not taken up

Address:

Haridwar, Uttarakhand, 247667

1. I get serviced my honda activa [ uk06p-5840] (Model feb/2012) from amar auto (Mob no. [protected]) roorkee (Hardwar) uttarakhand on 27.07.2017.
2.in that service they suggested the the work on engine is required and charged rs 7139 and told me to get it checked on 500 km running.
3. I used the vehicle as per their instruction for 500 km and get it checked at there service center. They simply took the test drive and told me that your vehicle is ok and come in the first week of december for service. As i was out of town during november

4. When today[protected], i reached the service station for service they told me that again the work on the engine is required. The running of the activa is only around 1000 km after 27.07.2017. How it is possible that after merely four month again the work on engine is required. Please look in to the matter and help me to solve the matter

I have attach the bill for your ready reference
