Hero Cycles — Faulty cycle given by hero cycles store

I purchased the cycle from Hero Sprint store CMR road, Bengaluru, HRBR layout. The cycle that came to my delivery location was totally faulty, my wheel alignment was faulty and my gear shift was not working properly. So, I have called the mechanic from store and he repaired the same on the very time when the cycles have been delivered.

I have used the cycle after one week to go to my gym and suddenly its chain got disengaged and i have to carry the same to the mechanic for its repair where he has pointed out that it's wheel alignment is not proper and cycle's chain has some issue.I have purchased two cycles and both are faulty one has chain alignment issue other one has wheel alignment and gear problems.

Two times because of this issue, I got saved from accident as when I was shifting my gear it was not working in the middle of the road due to which i have to stop my cycle in between and one time my sister's cycle chain got disengaged due to which she fall on the road and saved by the people in the middle of the road.

I am very much disappointed and really frustrated by the servicing and the kind of quality they have offered.
