Royal Enfield — Engine and shock absorber

Address:	Mayurbhanj, Odisha, 757041

I bought my classic 350 in august 2016. After second servicing my bike's engine sound is changed and it's very irritating. Like i drive an autorickshaw. And front shock absorber is not working properly. When i tell about that problem the dealer said leave the bike in showroom for work. But now already 27 days my bike is in the showroom. They does not deliver my bike. What can i do? Please tell me.
