Dell - Request for replacing with a new product

I recently had an issue with the dell product I bought in the month of November **** (Dell Inspiron ** ****,Service tag-*SLG***). I'm glad that the dell support team showed up to fix the issue and both the technicians who showed up were really kind enough to help me and did their job really well but at the same time I am a little disappointed in the quality of the product because within few months of buying the product, the motherboard, daughter board, cable and the display had to be replaced just to fix the issue regarding the microphone, speaker and the audio jack and I'm disappointed for the fact that these are all refurbished products except maybe the display. And unfortunately this is the second time the motherboard has been replaced. The first technician who came to fix the issue had fixed a DOA motherboard. The second technician who came fixed it, he again changed the motherboard(he changed for the second time), the daughter board , the cable and the display. My question is what is the point of me paying so much of money and buying a dell product when the product starts showing up issues within a year of buying it and also having to get these many parts replaced in just few months of buying it? What is the quality of the product that you assure? What if the product shows up issues after the warranty period? Isn't it going to be just a waste of my money? This is really saddening because the only reason I chose to buy from a reputed company like Dell is because I believed that it is of good quality and also long lasting and also the fact that I've used a dell laptop before for over * to * years, before buying the new Dell Inspiron ** **** and sadly the new one started showing up issues and now I have ended up changing these many main components to fix one small issue within a year of buying. And thankfully since it is in its warranty period I didn't have to spend money from my own pocket.
What quality is a reputed company like Dell assuring me now, for the fact that I had to get all the above mentioned parts replaced to fix a small issue, that too, within a year? Is it worth the money I spent for buying the laptop and trusting in a reputed company like Dell? Within *-* months the main components of the laptop had to be replaced, so how can I trust the quality of the replaced components from Dell?
Therefore, I request you to kindly look into the matter and take an initiative to replace this product with a brand new product , because it's not worth for the amount of money that I have spent to buy the product and now I cannot trust the quality and life of the above mentioned replaced main components of the laptop.
Looking forward for a positive response from team Dell.
