Hero Motocorp — Engine defect

WORST EXPERIENCE WITH HERO BIKE

I bought Hero xtreme 200R on 30th May 2019 in prudhvi hero Pvt Ltd, Tirupati, Chittoor (D) they sold me an engine defected vehicle, from the date of purchase, I have contacted dealer more than 30times, but there's no response.
If I give the bike for service they just charge money for service without doing any thing, they just change engine oil and wash with polish, they not even drive and test the vehicle, Even I have raised the issue in hero help desk, but, the dealers are forced me to close the complaint. I can't wait further, I need bike replacement or money back with compensation, please take it as high priority.
