I placed my order for my S21 on the 25th of Feb 2021 and have confirmation email of my purchase. Unfortunately the phone was out of stock on the 128gb option. I rang up to see if I they had any in stock and they told me they only have 256gb. I needed the phone quickly so agreed. I was told I'd be eligible for the free earbuds on initial point of purchase but now I've changed to the 256gb on the 01/03/2021 will I still be eligible?
