immediate action required: refund not processed

My name is Jader A. de S. I purchased an Alienware 32 4K QD-OLED Gaming Monitor - AW3225QF on March 14, 2024, Order Number  xxxxx in the amount of $xxxx. On March 18, 2024, I received a partial refund of $xxxx because of a promotional discount which was applied to my purchase total. Credit Memo number: xxxxx. On March 21, 2024, I contacted Dell and requested a full refund of my purchase in the amount of $xxxxx (total minus promotional discount) because the monitor screen was scratched due to poor packaging. Dell sent me a shipping label. That day Dell had a problem generating a case number for the return and I was given more than one case number for the return. I returned the monitor with the shipping label number xxxxx on March 22, 2024, and Dell received the monitor back on March 26, 2024, which was confirmed via the tracking number. I contacted Dell customer service several times as you can see below because I did not receive confirmation of the receipt of the monitor in my Dell account. Dell customer service confirmed receipt of the monitor every time and gave me a new case number each time.  Dell customer service informed me that it would take up to 10-15 business days to process the refund in the amount of $xxxxx, but I did not receive the refund. The last case number is the most recent. Please see refund order number below with authorization number. On April 20, 2024, I received an email stating that a refund in the amount of $xxxxx was processed by Dell, but I did not receive the money into my bank account. I contacted Dell again to inform them that I had not received the refund and the support person said that the refund had been processed and they could no longer assist me and to contact my bank. The purchase was made through PayPal, so I contacted PayPal and explained my situation. I provided PayPal with all of the supporting documentation they requested and they informed me that they had never received a refund request from Dell in the amount of $xxxxx only the refund amount of $xxxx. The also informed that they could see a purchase amount but not for $xxxx but for $xxxx. When I followed up on my dispute PayPal informed that the dispute had been closed and in favor of Dell. Is this because there is a discrepancy in the amount that Dell should have refunded, and the amount PayPal has in their system? It has now been 3 months, and I have not received my money back and I have been unable to receive any assistance from Dell or PayPal to resolve this problem appropriately and fairly. I have been more than patient, but I am now demanding that I be refunded the amount I am due and in a timely manner. I did all that was requested of me and within the time frame that is required for a refund. Thank you for your prompt attention to this matter.
