Address:

I purchased a cycle from this store which is having manufacturing defectwhich i noticed but they repaired it and the store assured me of change if the problem persists. The cycle start giving bubbling after two months from front tyre joint which i tightened in the same way they get it done at the time of selling but it again started bubbling after one month then i visited the store and told them the whole issue but they ignored it and repaired it without any permanent solution and again promise me that it will not happen again but now it is happening after every 5 to 7 dayswhen i visited the store they refused it and repaired it minorly but the defect reoccur after 5 to 7 days. Till now i visited thrice the store but nothing positive happen and i m suffering because every time it is very tough to transport the cycle to store which is far from my residence and the cycle is of my son who is 7 years old
