Samsung not delivering on their promise

I bought a new Samsung S21 for my son, following a disappointing incident with his previous phone. Part of the excitement was that he qualified for the promotion of receiving the galaxy buds live. As a teenagers, listening to music is part of their life... It has been more than 6 months since we bought the phone, and registered for the promotion, but till today no delivery has been made. Every time we follow up with Samsung it is the same old story. They ran out of stock, or they blame the courier for messing up. But other than making excuses, they don't seem to care about the customer. This became a real disappointment, especially for my son, as he was looking forward to enjoying the new phone with the buds. Unfortunately Samsung messed up this dream. I don't think they realize the damage this can do. As a youngster, these people have a different view on life. He already told me that for his next phone, he will not be taking a Samsung, as they are not focused on customers, they only care about sales. What a disappointment.
