Tvs Motor Company — rtr apache 160 battery problem

Address:

New Delhi, Delhi

"hello"
I purchased a rtr 160 on june 8, 2017. But in the course of two months, his bettry got spoiled. From 3 days i have given him the replacement of the battery in k. K. Tvs service station, udhyog nagar, nangloi, delhi. But so far the battery has not been changed.
Due to bad battery, motorcycle was not even started. I had to pull a motor bike for 20 kilometers due to this. I'm having a lot of trouble.
Kindly solve my problem.
