Dell needs to fix its paypal

This has been a recurring issue with older users according to this website. I was ordering 2 laptops for my family and used my card, however I accidentally ordered two orders, hence like any normal reaction I cancelled the order. Yet Dell rebills me again and again through PAYPAL. It is stuck as temp authorization in progress. I have not received any help yet and have created many tickets. Never buying dell again no one should be forced to go through so much it has been over a month and my credit card has a huge 1.856k mark in its face which is super annoying.
