Non commitment to Promotion

I purchased a S21 earlier in the year and part of the purchase was the promotion for galaxy buds and a galaxy tag. I redeemed the promotion as per instruction and get an email to confirm it. I the contacted the call centre a few weeks who told me I must redeem again with a receipt with the IMEI, which I did. Once again waited a bit with ni luck. I contacted the call centre to be told I was on the dispatch list so waited again with no luck. So I tried email support who said I must email the corrected slip again as it was not approved. I am tired of running around in circles. There promotions are just a ****. However I am enjoying the phone.
