Dissatisfied customer and poor service

I placed my order on 2 September 2024 the delivery date was the 10th and I haven't been updated about my order. I have been going back and forth with useless agents and supervisorsr cause they not giving me any info. The shipping status was last updated on the 3rd so my order has been with the carrier since the 3rd I asked one of the agent to call the carrier company instead she gave city logistics contact details so that I call them, I don't understand why should I be calling the carrier when the error with between mrp and the carrier, they haven't delivered my item and they also don't want to cancel it since it's out for shipping. How long should I wait????
