Address:

600007

Purchased an woodland women ballet shoes on 20/08/2018 for rs 2895 in woodland showroom - express avenue chennai. The shoes almost drilled a hole in my ankle and were the most uncomfortable pair of shoes. The company's return policy stated that return o[censored]nused goods within 7 days. But in this case how am i liable when the defect is known only after using it for a day.
