XPS 9530, defective product, 6 months troubleshooting, exchange it

I ordered an XPS 9530 and received it December 9, 2024. Upon taking it out of the box, the screen has been glitching, going black occasionally, and there are horizontal lines appearing on the screen. I have been in contact with technical support since (6 months of back and forth) and the issue is still not resolved. I have spent countless hours trying to fix this issue, and have wasted my personal time, effort, energy, and money on this despite not being responsible for the damaged product. It is absolutely ridiculous that if I pay full price for a product that I instead receive a defective product and am then responsible for fixing the issue. After 6 months of troubleshooting, it is reasonable to expect that Dell should replace the product, since it is clearly defective, but they refuse. I am not being compensated for the time I have wasted trying to fix a product that I didn't even break. Customer service was absolutely indifferent, and blatantly told me that the best course of action I could have taken was to not purchase a Dell product in the first place. I expect at this point to be refunded or have my machine fully replaced. After 6 months of trouble shooting, the issues with the screen still persist. In addition upon taking the computer out of sleep mode, I have a black screen and I cannot access the login screen unless I manually restart the computer.
