Samsung Refused to replace item still within warranty

Bought a Galaxy S10E 9 months ago. The included Earbuds stopped working a couple weeks ago and are still under warranty. I contacted the company to get them replaced, and they sent me an older pair (the kind included with the S8).

I contacted them again to explain, and was told numerous times over the course of three hours that these were the same earbuds (they are not). Finally after speaking with a supervisor I was told they would have someone contact me within 72 hours regarding the matter and that the correct Earbuds would be sent.

Lo and behold, no contact for over a week. Called again, was told that they couldn't do anything to help me.
