Not happy

Purchased a stove in Amazon and no disclaimer that it’s was through a seller and that cancellation is different and you have to wait for the seller to confirm cancellation and I cancelled it on Sunday on the app and followed up through an online chat apparently cancellation online don’t matter because it has passed the 48 hours and the seller has not confirmed anything and seller no one wants to provide a direct number so I now to wait wait for a cancellation confirmation which is insane considering it’s delaying me getting my refund back. I am not happy and should be a full disclaimer on Amazon of cancellation processes before it allows purchase and who you actually purchasing it from and how that will impact you should you be unhappy. I got a run around as to how Sunday cancellation is not seen only the one that was absent by an agent clearly indicating that if I did not follow up the order would not be cancelled very wrong. I need that cancellation confirmation please and when I ca expect my refund
