Hewlett Packard 8500 Premier (CB025A) All-In-One InkJet Printer

I purchased this printer on Oct 30th & immediately the wireless radio signal didn't work. I called HP & they convinced me to troubleshoot & keep it. It worked for 3 days then the radio went out again.  I contacted HP several more times via Chat & they promised to send me a replacement so not to take back to the store. They were supposed to call me within 24 hrs but I called a week later when they hadn't called. They wanted me to troubleshoot again & finally they authorized a replacement. Every time I contacted them, I was on the phone or chat for 3 hours.  The replacement arrived one month after I bought the first printer & the replacement has defective Hardware & doesn't work. Now after 4 more hours on the phone & chat they want me to pay for shipping if I want a new one in less than 10 days!  ridiculous. The supposed supervisor barely speaks English and refuses to let me speak to his superior. He insists that I should wait 10 days for a new replacement when they screwed up & I've already waited 3 weeks longer than I should have due to their incompetence.  HP is a joke when it comes to customer service. This is the LAST HP item I will ever buy!  I may have to hire an attorney to get my money back since this was a $500 piece of JUNK!
