Problem with my galaxy tab claim

I bought the Samsung s23 on the 23rd of February. Dane day i submitted a claim for the galaxy tab. I received an email that the was an issue with the proof of payment. I them asked for a PDF version of the tax invoice from the store and sent it and to this day I haven't received any feedback. I tried calling and after holding for more than 20min a gentleman picked up and just dropped my call. This was the back and forth I experienced with the buds claim until the promo ended.....
