Royal Enfield — bad servicing of re bikes

Address:

South West Delhi, Delhi, 110043

I purchased my re350 on 20sep18 the first servicing is due on first 500 kmart or one month whichever is erlier. On 02 dec 18 i visited re service centre outer delhi showroom their service is very poor they didn't change engineoil but charged 600rs but they didn't. After servicing a different noise coming from engine but earlier there was no noise coming. They make re customers fool and charges are too much. Please do something
