Pathetic service from samsung

I upgraded my account with a new Samsung Note 20 phone on the special where you get a Samsung tv. We upgraded the upgraded the account in Oct and Samsung confirmed the receipt and the activation of the tv deal and said it will take 4 to 6 weeks for delivery. Its now march, 5 months later and no word from samsung. I called them repeatedly and they keep on saying they will sort it out and get back to me. They never do. Pathetic service. Samsung even said that they themselves canceled my tv deal because it took to long. How can they cancel it if its they thats making it take so long. I have been a huge supporter of samsung for as long as i can remember and only ever buy samsung phones and tvs. But this is PATHETIC service from a big brand name. MTN that i upgraded at has also been extremely unhelpful in the whole process. Who can i contact at Samsung to help with this.
