Help! Premier support won’t!

I will never buy another Dell if this doesn’t get fixed!

Bought my child an XPS13 for college. Bought the premier service plan so that if something happened they would fix or replace quickly so that he would not be without a computer.

Motherboard broke within 30 days before he even left for college, computer replaced.  Motherboard broke again last week.  Part is not available so they can’t fix, and they have no timeline.  They just keep saying they will let me know when it becomes available.  They will not replace it.  They won’t refund my money.  

So, my kid is stuck.  He’s at college with a broken $1500 computer and service plan and no way to rectify the situation.  

Online support will not give me a supervisor or a corporate contact.  

Help!!!
