Ear Bud promotion

I bought a Samsung S22 and sent in for the free earbuds promotion. On the 13th May I received an email stating my claim was successful with a reference number. I have a friend and a family member that also submitted at the same time. They both have already received their ear buds. I have phoned numerous times to check on my delivery to be told it hasn't been processed yet. I have been told the matter has been escalated but to date nothing. I cannot believe it has taken over 3 weeks to sort out a delivery or that Samsung has had no stock for that long. The last person I spoke to was Veronica in Samsung Promotions who said she would escalate it to her manager and he would call me back (I have heard that 3 times now). Please can someone call me back to sort this matter out as soon as possible.
