I bought a BRAND NEW DESKTOP from Walmart and received it June 1st 2021. I went to the HP assistant and it shows I have NO warranty as it expired 9/7/2020. HOW CAN THIS BE? You would think after I registered it, I would have a year warranty! I filed 2 dispute claims that are being IGNORED!! I have always bought HP! I have a HP desktop, a HP monitor, and a HP printer. I am very UNHAPPY at this point. Has this warranty issue happened to anyone else? Why do I NOT have a 1 year warranty????
