I upgraded from Apple Watch Ultra 1 to 2 in October 2023, paying off $200, but instead of receiving a $200 credit, I ended up paying $200 without receiving the device. Despite contacting customer service, they claim I received it. They assured me the credit would be processed between billing cycles 1-2 from October 2023 onwards. Today is March 2024, yet they insist the credit will be processed within 1-2 billing cycles. I requested Verizon to return my Ultra 1 watch, but they refused. This situation feels like Verizon has stolen my watch. How can I resolve this issue?
