Empty Promises

I've bought a new Samsung A54 and watch 2 months ago. I was told I can claim my free earbuds from Samsung Promotions. I went through the registration process and was told my claim is successful. I received an sms on 28 April 2023 to inform me that Courier It was unsuccessful to deliver my earbuds. Firstly I wasn't informed prior delivery when to expect the delivery and no one even tried to call me when they arrived at the address to say they are there. If I was notified before delivery I could have told them the address is my work address and it's at a school and that the 28th of April was a school holiday day and I could have given them an alternative address or have met them at school. I've called Samsung Promotions 4x times since then to explain what has happened and every time they tell me it's been escalate for re-delivery... up to date no one can tell me when will they deliver. I've even send numerous emails to Samsung with no response.
