I have ordered AT bagpack during myntra sale for 841, and it is supposed to be delivered by 27 june. But it shows technical error still I waited till today (9th july) and they said they cancel the order due to the technical issue and the same bag now shows for 2300 on myntra itself.
even my order was prepaid.
This is not at all justice.
Give me the solution.
I can not spend more money and want same bag because every day (since last 15 days ) despite of hectic schedule i managed to check the status of the bag and eventually I found that they are refunding my money. I want bag.
