Hello,   I’ve trade in my Dell Inspiron 15 laptop a month ago. The trade in status has never changed from “Trade in started” since February 20th. Customer care numbers are not working. Is there a way to contact Dell? Did anyone face the same issue?  Thanks,
Dell Trade in started February 20, no movement?
