Flipkart — Iphone 14 cancelled with no reason

I've ordered iphone 14 in big billion sale . It's expected to be delivered by Oct 16 from that date we are trying to call Flipkart delivery agent and after several attempts he finally picked the call and ask us to go to Flipkart office to receive my order . We went there and mythey shown our order and they said they can't issue due to technical issue. And it's been 7 days my order is not delivered and this seller has simply cancelled my order . What the hell services you guys are providing ? I've paid full amount from credit card and I won't leave this guy's .. I'll proceed with consumer court and file this issue
