Hero Motocorp — engine abnormal sound since I purchased

Address:

M/S. VIMCO AUTOMOBILES, NEAR HOTEL NYAY MANDIR,N.H.NO-8,,BHARUCH- 392 011, 392001

I bough my meastro edge on november 2015. I found meastro edge logo stick wrong way while technician was fitting accessories. I request dealer to replace my scotter as it was still not delivered but they said we will inform production department ans they will send new one and we will replaced. Then they replaced it during my first free service. But the main issue started after first free service. I heard abnormal sound during ideal condition as well during engine run condition. I immediately took my scotter and they found no oil in engine. This was next day of service. They said drain bolt was remain loose so all oil was drain out. They make everything ok but since then my engine is making abnormal sound and average is so poor. I mentioned this issue in each every service there after but till today my problem is not solved. I doubt that qc of my scotter was done properly during manufacturing process which resulted in engine problem. Wrong logo stocking is the one of the example. Now i want either hero replace my scotter or at least engine.
