DELL SUCH A DISAPPOINTMENT

I paid a lot of money for a Dell Inspiron 15 7000 Gaming Computer in late November 2017. Therefore, the laptop is just over 3 months old. The cable has a design flaw and it has already worn and cracked off in a join! I am furious. Not only that, but Dell are refusing to cover this under Warranty, saying that it is "induced" physical damage! I want my cable replaced by Dell with something that is not going to break in the same place in the same way, from wear in a few short months from now!
