I wanted a Dell with 16GB of RAM and a USB-C port so I can connect to my Dell docking station.  The computer arrived and it looked brand new.  After a few days I realized the keyboard is not backlit as advertised.  I called the seller's support line and after much discussion they realized the keyboard was not backlit.  They were very nice and the fellow offered to exchange the laptop but I declined since I had already loaded up several software applications.  It would be a hassle to ship his one back.  The fellow said they would give me a credit of $10 to $15 since the product was not advertised correctly.  I am not sure that ever happened.  They were helpful and I really like the laptop.
