Stylus for my 2 in 1 Inspiron

Dell rant.... after a long time customer I am so disgusted. Purchased a stylus for a laptop as directed by Dell chat. The stylus did not work. Having paid premium support, was told to backup to external drive, extra $$, and upgrade to windows 10, hours and you guessed it more$$$, then an hour with tech support updating drivers, still not working, transferred to floor supervisor, "they told you to order wrong pen" transferred to sales... hung up on me because they weren't open at that time. Call on Monday, oh this is the correct stylus, I asked why did tech support say a different model? Please hold.... oh I made a mistake,  this is the right one,  seriously.. when I got livid about the exchange process they transferred me and the supervisor said the previous person was wrong again it's another one.  Still on hold after 1 hour 20 minutes and still waiting to verify getting a shipping label. Where did the good Dell go. My student stilll needs a stylus for college and I don't have a clear answer. Now the laptop is back at college so all I gave is the service tag number.
