The warranty date issue has nothing whatsoever to do with "loyalty".
If I understand what you're saying, you bought the PC on October 14th 2019, right? And the warranty expired date said June 15th, 2019. The warranty date is set when the PC is BUILT, not when it is SOLD. So, this PC was built in June of 2019. What you have to do is register it with HP to then have the warranty start date reset to when you bought it. I'm guessing you did NOT do that, as you did not mention it.
We can not do anything about you NOT registering it -- you will have to take this up with HP directly.
