I traded my iphone X for the iphone 12 and see the tracking shows delivered to Apple March 17th. How long does it take for the credit to post? I honestly do not know if I should contact Verizon or Apple. I called Apple to get who recommended I go through Verizon as they had a better deal. I paid $200 deposit on the phone and supposed to get at least $250 for my phone off the cost of the iphone 12. I could have gotten more off but refused to switch my cell phone plan from the 55 plus. The box to mail it in came from Apple, I picked up the phone at an apple store. I honestly know I should be patient but it drives me crazy the unknown. Should I call Apple or Verizon when the times comes?
