Dell G15 5510 - Wrong specification

Hey all,

On November 2021 my brother bought me a Dell g15 5510 laptop, because i thought the specs are great. However 1 month after buying it I've realized that specifications were actually wrong for the gpu.

In Dell specifications it is stated that 5510 have a 115W rtx3060 but it actually has 90W rtx3060. I've been trying since December 2021 to convince Dell that this is actually wrong, some of their technicians actually agree with me and they file a refund request but some of them just say that there is only one type of rtx3060 (non sense) and i have the correct one. Eventually, my refund request is declined.

I've attached required links and images. What should i do in this situation?
