Dell Support has been unhelpful, made my G15 5530 worse and wants me to pay them to fix it

I purchased my computer in late October of last year (G15 5530 October 18, 2024 with a 1 year warranty), and began having issues with it in May. The only issues I had were flickering lights and other graphical errors when playing games, and ONLY when playing games. I contacted Dell's support and opened a ticket with them. Throughout this entire thing I have been bounced between at 5 different agents, and been ask to do the same things multiple times by these different agents. Some of the attempted fixes actually caused further errors. I was told that, through device manager, I should select to uninstall my gpu. This caused significant lag in regular use, not just during gaming.

After about two weeks they finally determined that it was a hardware issue, and not a software issue, they told me that they would either send me a box to mail it to their depot, or take it to a designated store that would send it. I chose the second option, and I was sent to a store where I was told that they had never performed that service, and the Dell Support had been told this, and not updated their information. So I requested a box be sent so I could mail it to them.

After sending it back I was notified that it would take longer to repair than expected, since they did not have the necessary parts in stock. However, later that same day I was notified that the repair was completed and I would receive my laptop back within the next few days. I am unsure why they claimed they did not have the part, but suddenly were able to repair it that same day.

After my laptop was returned I could not verify the issue was fixed because any game I tried to launch had extreme lag in the main menu, and when trying to continue, any games would not load. Over the next couple of weeks my computer displayed further issues; lagging during general use, crashing/bluescreening multiple times, overheating so badly my computer forcibly shut down (which had never happened before), the battery rapidly draining when not plugged in, battery rapidly draining when it IS plugged in, brightness only changing on computer restart, the computer freezes during restarts that have lasted up to 10 minutes, and the case was not properly put back on. None of these issues were seen before I contacted Dell Support for help.

After seeing and trying to fix these issues myself, I contacted Dell Support again. I was called, put on hold for most of the call, told that it is most likely a software issue, and told goodbye. After the call I received an email saying to try and factory reset my computer (which I had done, and had been told to do 3 or 4 times in the past month). When told that I had already done this during my attempts to fix the issues, I was told that it is a software issue, and therefore not covered by my warranty. A reminder, they did not fix that I contacted them about, and caused the issues I am now contacting them to fix. Now, they are telling me that in order to fix my issues I need to pay them.

I'm sorry for the wall of text, and I'm sorry if this isn't the place to post it, but I don't know what else to do. I hope this doesn't get taken down, and I can understand if it does.
