Delhivery — Was delivered a fake product

I received a consignment through Delhivery that was ordered on Silk Plush. I paid through scanning QR code. But turned out that the product was not as mentioned in the cover. I reached out to the delivery personnel who directed me to his store manager. The store manager claimed that the money paid through QR code will be credited to the sender directly and cannot be reversed. However, my bank intimated that the money was credited to Delhivery’s HDFC account. If I am a victim of online fraud, is Delhivery a mediator for the transaction? If the company can’t afford to stop crediting the sum to a fraud, does it claim that they don’t care about what’s inside nor who sends it? So any fraudster can use Delhivery as a tool? The whole delivery team was fooling around claiming to help me but then backed off, when I intimated them that I have raised a complaint with the bank about it.
