Hero Cycles — hero dtb spur

I have bought a new cycle for my kid on 14.6.2017 from jaswant cycle store, railway road, jalandhar. From the day one, i am facing the problem with cycle, in the last one month, the brakes got damaged 8 times, 2 times brake pads need to changed. Further, chainset got damaged and broke 2 times, i just wonder is this the product of reputed brand "hero". While contacting dealer, he is not ready to listen, every time he is saying "aisa ho hi nahi sakta".in case you need to get the same repaired, bring it to my shop which is not feasible for me as same is 15 kms from my place and in case, we decides to reach there, there will be a cartage cost of approx 400- 500 rs, who will bear this cost. I urge to kindly get my cycle replaced as the product sold to me is not of proper standard. Need urgent action on same.
