Earbuds not delivered

I am totally disappointed. I took two Samsung A56 phones which came with earbuds. Only 1 set of earbuds was delivered when I asked abouts the second 1, I was told it would be delivered the next week. 3 weeks later I still haven't received the earbuds, I am getting no assistance from the store and the Samsung consultant that assisted with the claim for the earbuds. They are not responding to my Texts or calls. I need urgent assistance.
