Very bad aap and not at all ethiclal.I ordered a Titan EyeX smart glass and applied Kotak bank coupon of 10% discount for Rs.1000. Paid Rs.8999 and estimated delivery was 5th Mar which got pushed to 7th.On 7th order was cancelled for no stock ,even though product was available on the app through this period till date. Now the coupon is not accepted again and no discount offered. Never expected this cheap tactic by TATA group where they lure,cancel orders and not hold their commitments.
