Samsung not delivering on promotional gifts

I have beem waiting since February for the promotional gift of ear buds that they offered with the Samsung S21. Every 14 days I call, i get a soppy story about short stock. That has aparently been sorted and every time they need to verify my order and then promise they are sending my ref number and order through to the delivery team. Then I wait 14 days and nothing. Repeat the process. Sam story every time. This is the worst service that I have ever received from this trusted brand.
