Hero Motocorp — hero motors losing faith of indian customers

Dear sir/madam

I am Tarun Malviya belongs to mehragoan it is small village in Itarsi tehsil.
I have to inform that your company is losing our faith because I had purchased a hero maestro edge before 3 year I am continuously serviceing it only one service was missed but yesterday dropping oil and abnormal sound check service centre technical person said engine shaft bend & oil seal leakaged and he open full engine and send for repair. I had asked questions to technical person what is reason of this problem he said this is machinery part problem was came or this problem may comes in long time of period.
We will not suggest purchase of any hero motors bike because of such short period engine failures and bill was 3823 and I have also attached a bill copy.
