Hopefully someone can help me. I've been with Verizon for over 5 years now. I bought 2 Samsung galaxy s10e when they had a promo of buy one get one free over 24 months. There were billing me and crediting back on the free phone. Fast forward to today. I still have 8 months left and decided to pay off the one and bought but accidently paid off the free one that they were crediting back every month and now I still have a balance on the phone that I actually owe on. I've called customer service and pretty was told I was out of luck. Its was a mistake I made and I get that. Any advise would be much appreciated. Thank you.
