I think you should punish your father.   
 
Get a good paddling spoon and explain why he should make better decisions.   
 
Just a question.... Why has your dad ditched this on you so soon after.  Only a week?   
 
Let him deal with the sale and care.  Lesson learned.  
 
Maybe your LFS will take them back.  Credit perhaps.  Any reputable shop would consider rehoming something like a ray than leave it in poor hands.
