AkshayJ can I ask are you trying to claim the buds pro or the buds live? The reason why I ask is Samsung had a free promo offer for buds pro and were for those who pre ordered the s21 ultra between the 15/01/2021 - 29/01/2021. I know that they've done a similar offer with the buds live after the dates I've just said.
I could be wrong, but if you ordered directly from Samsung I think they send the free gift out with the phone. I didn't think you need to claim only if you purchased anywhere other then samsung. When I ordered my note 20 the headphones were sent out together, ordered the buds Pro from amazon I had to put a claim in to get the free gift.
@AkshayJ don't worry you'll be able to claim them as you've made your purchase before the end of the promo date and as Fiona said it was direct from Samsung. But I totally feel you, because this was not a simple process. I am waiting on my buds pro to come and that's because I got my phone through 02. But fair play to Samsung they've kept me updated. Hopefully you'll get your phone delivered soon along with your buds live.🙌🏿
