Dell sales representative lied to me to sell their product

Dell sales representative lied about the compatibility of the Samsung 970 evo SSD with Alienware m15 to sell it me. The sales representative told me that it is “perfectly compatible with the laptop”, but my laptop’s screen went black after I installed it and I had to push the power button to restart. So I called a technician of Dell and he said that “eco SSDs are not compatible with any alienware”. He transferred my call to the costumer care who only wanted to passed the buck by by telling to call the technical department again. They just told me to return the product without any action taken to respond to their dishonesty. It seems that they have no idea how much money, time and energy their dishonesty has cost me. I had to buy a screw driver and look around the stores for a screw to install that SSD. They even don’t have a screw on the second SSD slot.
