So return your phone and buds and get nothing! If something is free, be grateful. I believe Samsung ran out of Buds Pro stock so they can't magic something they don't have.
@Shak44 it seems that you quite probably missed the 'pre-order' date. If you purchased your S21 ultra phone before 29th January and before public launch then you would most likely have received the Buds PRO.
If you purchased between 29th January and 25th February then you would have received the Buds LIVE.
If you purchased the S21 or S21+ then it was always the buds live.
It seems to me that you may not have read the terms and conditions. What date did you actually place your order ?
I am also assuming that you did NOT place it directly with Samsung, as those of us that did order direct from Samsung, had the buds and tag supplied straight away. It was only the order with carriers and external from Samsung that had to claim and wait 45 days.
There is a lesson to learn. Make sure you always read the small print.
