I have bought the questartf (Aq6632) shoes for rs 9299/- on 14.02.2017. It is an expensive shoes atleast for me.
Its one eyelet is broken and even throat material is also torn simultaneously which is prima facie is big manufacturing defect. After complaining to the store on 11.08.2017, they said we will lodge the complaint. Yesterday they communicated that the complaint dated 18.08.2017 is rejected due to the fact out of warranty.
It is learnt that they might have have not correctly described the defect.in your communication (Copy attached) you mentioned that the shoes is out of 3 months warranty.
Can you please explain that such an expensive shoes are manufactured for 3 or 6 months. Due to the defect the laces can not be passed through the eyelets (Images attached) and shoes can not be wore in present condition.
Shall i throw away such an expensive shoes in 5-6 months.
