I have a Panasonic mdl

Question

I have a Panasonic mdl CF18KDHZXVM and need the power port mdl. DL3U3B471AAA. It was back ordered for 3 weeks by the Parts Store until they finally told me it wasn't available. I called Panasonic who refered me to Heartland who referred me back to Panasonoc. I've gotten over seven different numbers and no results. Can you tell mw where I can obtain this part or it's replacement? I'm rapidly losing interest in purchasing additional Panasonic units. I have an inspection company and this computer has been unusable for six weeks.
