Free Gifts never received,

i upgraded my contract to a samsung S21 ultra, and i am still waiting on my free gifts, ***, i have not received it yet, i call and email every month but gets asked the same question, did i send my invoice, yes and received a response from samsung stating it was received and revalidated. Miraculously validation is found and the next excuse was covid, next excuse no stock. i dont accept any of that, i received shipments in lockdown, stores have stock available to sell, so are we loyal samsung supporters not recognised?!!!!!.

How can you tell your clients that you dont have stock when there are stocks in store freely available.. this is utterly ridiculous, i have to phone and email on a regular basis or noone gets back to me with an update...

i do not understand why i have to struggle like this, free gifts should be given with phones when we purchase it.

please advise!!!!!!!!!!!!!
