Samsung Free Buds

I upgraded my phone to a Samsung A31 and was supposed to receive free Samsung Buds as part of the deal. I Downloaded the Samsung Members app and couldn't find anywhere to redeem the Buds. I see that other people are complain about about the same thing. I wasn't told of any end dates or limited quantities during the upgrade process. I specifically went for this contract as it had the buds and now being told it limited quantities. This is false advertising
