*****, advertise new, but got old used model

I sent an email to them and asked which iPhone SE it was, they never rep****; but I continued with the order anyway. Upon receiving the phone, I sent an email again asking about the model and why it was used, the answer I was given was that it an iPhone SE. I also sent them an email on Facebook, but that too produced no results. My frustration comes from the for fact that the description said it has a A15 Bionic chip (see previous attachments), which comes with the iPhone SE 3, but I was given a used iPhone SE 2 (which comes with A13 Bionic chip).
