Desktop Hardware and Upgrade Questions

On Mar 14, 2021 I bought a PC from HP. The specs:
- Nvidia RTX 3090
- Intel 7 10700K 3.8 Ghz
- 16 gb HyperX RAM
- WD Black 512 GB PCIe SSD
- etc

I paid a total of $3065. On the same date I could have bought a PC with the same specs (and no OEM parts) from ibuypower.com or cyberpowerpc.com for $500 less. The reason I went with HP is because their shipping date was Apr 09, 2021. All the other brands could only offer these specs by May 06, 2021.

By Apr 08, 2021 HP had not updated anything on the order page, so I contacted their support. Their support person assured me my computer was still being shipped on Apr 09 2021, to wait 24-48 hours and then contact them again if there was any problem.

By Apr 11, 2021 nothing had changed and I had not received any notice of shipping. I contacted support, and the support person assured me again my computer was shipped on Apr 09, 2021 and to wait 24-48 hours for the tracking number to arrive by email.

I have the logs of both conversations to show this.

On Apr 12, 2021 I received an email from HP saying "As a direct result of unexpected supply constraints, we now expect your order to ship on a revised date of  4/27/2021". Which basically means I will now be receiving my PC at the very least by May 06, 2021. That's if I'm lucky, which I know I won't be because this is what HP does and they knew perfectly well that they would not have a supply of 3090s before May 06, 2021, just like everybody else. In addition to that, my credit score took a noticeable hit from spending the $3065.

So far I'm $3000 poorer, had to pay $500 more than I needed because of their shipping promise, I have no computer for a month and a half (if they actually deliver on time) so I'm losing money because I cannot work for 3 more weeks, and I cannot cancel the order and order from someone else, because now prices have gone up for everybody and to get a PC with these specs you have to pay at least $3900.

What is HP prepared to do to compensate me?
