I bought a Z fold 6 during the pre-order promo deal. During the process of purchase, Samsung REQUIRED I pay off my trade-in to complete my purchase. I did as prompted THROUGH the Samsung website. The mistake I made was assuming that Samsung would communicate with my provider that the trade-in device had been paid in full. THEY DID NOT! Even spoke with Verizon, whom said Samsung is the responsible party since I purchased through them. I have contacted Samsung countless times about this issue and they say it's Verizon's issue. It's a broken record. Unfortunately, I chose to use the Klarna option and pay my new phone in 4 payments so there is no record of paying off my trade-in. I've lost $450 to Samsung and am still paying for the trade-in with Verizon! CUSTOMER SERVICE IS JUNK!
