Warranty dispute process very convoluted, warranty flagged incorrectly as expired

[fargbargle]

I purchased a new desktop on 5/7/20, but HP has guesstimated a sale date of 1/8/21 instead and marked the warranty as expired.  

I opened a warranty dispute case (Case ID: 5063126779) after trying over half a day to get the site to register it. But there is no timeline for any action on that, and no update so far on the website.  I called the support phone line and read off my serial number, I clearly stated O(letter 'oh') and the automated assistant read back a 0(number 'zero'). It told me it didn't find that serial number and told me to call during business hours or go to the website.  The HP support website is full of dead end links and another useless virtual assistant.  

I just want to talk to a person, to get the case moving as I need to also file a repair case after this.  It's ridiculous to allow online case submittal but to give no timeline for review action and to endlessly redirect to virtual assistants that appear to be designed to waste time rather than to provide any assistance.

Hmm.

5th of July in 2020? 20th day of July in 2005? 7th day of May in 2020? 

8th day of January 2021? 1st day of August in 2021?

Is the mixup in dates to your advantage?

A one-year warranty starting on 5/7/20 should still be valid until 5/7/21, July 5? May 7?

A three-month warranty starting on January 8 2021 will expire on April 8 2021, which is still in the future.

A two-month warranty starting on January 8 2021 expired on March 8 2021 (11 days ago).
