Dell has the worst customer service!

Most computer/software companies work hard to make a good impression on computer science majors in college. Dell dropped the ball with my son. I bought my computer science major son a top of the line dell XPS 15 computer and added a 3 year premium support for another $400. Last semester while the computer was under warranty the laptop would experience a freeze of the mouse/touchpad when tilted 10 degrees on one side. My son was busy with his studies and did not tell me about this issue but graduated last Saturday Summa *** Laude as part of the honors program. he bought his dell laptop home and told me about the issue. I called dell tech support who said the laptop was a few months out of warranty and we were on our own. I called several times and transferred several times and finally reached the escalation department. Bottom line was dell cares more about their profit than making a good impression on a new computer systems analyst hired before graduation by a 14B US company. If it were me I would have made an exception and left a new computer scientist with a good impression of dell instead of burning all bridges and leaving a nasty taste when either my son or I (a 27 year computer scientist) thinks of dell. The issue is a hardware issue and likely due to poor manufacturing. Be warned and avoid dell and especially dell customer service who could care less about the customer.
