Hero Motocorp — hero spl ismart 110 drs cw

Myself anirban santra, purchased a hero spl ismart 110 drs cw vide engine number is ja06ephhc04317 on 16th august 2017 from das traders, ghatal, paschim medinipur. After three days of purchasing engine fault is detected. After some days of repeated calling to hero moto corp service center-ghatal they have changed the engine kit, i dont know is it original kit or not. How it is possible to change kit after 10 days of purchasing. Now the engine oil is coming out from the engine. I have already visited the service center three times in a month. It is not possible to visit service center everyday because i have purchased only new bike. How it is possible for a new purchase bike?? I dont konw how hero moto corp is selling this type of bike?? Service center is near about 40km from my house in one side. I have lost faith from hero moto corp. I have purchased my bike through cash payment. It is surprised that after duly payment m/s das traders has been sold a faulty product. After that they are not responsible for this. They are selling only for money. Request to hero moto corp to look at this matter carefully & resolve the issue as soon as possible other wise i will go for court case.
