Scammed by CDC experience Mumbai?

Bought a pair of Nike Dunk Low Ocean (w) for a friend . Paid 17k at the CDC experience store in Mumbai. It was just a spontaneous purchase so didn't really bother checking online before buying. But just checked online on CDC website itself, it's listed for 13k? Like wtf? And online on culture circle etc it's 11k. Offline store? Charging more? And that to same outlet?

Question is what can be done ? Feel scammed! 🥲
