Dell denied my return request due to few days passed the deadline

Today is the two month since I purchased / received my "new " laptop, but the issue of Blue screen/shut-down itself  started at the second week after I received the laptop.

Dell denied my return request due to few days passed the deadline. I told them I had never thought about returning the unit when the issue first occurred as I trust DELL so much ! I thought the issue should be gone after software was updated.

Now, It has been 1.5 months that I have been dealing with the malfunction of my new laptop using my work computer to handle this issue. My family members and I had to take hours off to accommodate the technician's service schedule. After 4 times of online service(software update / re install OS)  and 2 times of in person service(Replaced MOTHERBOARD and SSD), the laptop is still not functional as of now sitting in the box. 

Sales Manger, Dante finally got back to me after I sincerely asking his help to get me out of the situation. They agreed that they will try to approve the return request with re-stocking fee applied.  

It is a $2000+ computer, with the hassles I have been through, I am really disappointed about this purchase, however , I am very satisfied with the service support from DELL online/ on-site technicians (Elizabeth Q) ,  and Sales Manger Dante's genuine help. 

Hopefully,  DELL will help me out of this situation asap.  Fingers crossed!
