I selected to ship my old iphone through UPS. On May 5th, I dropped off my old iphone through UPS. UPS scanned my QR code from Verizon. As of May 22, Verizon has yet to received it. I called Verizon to find out status and Verizon was able to provide a UPS tracking number. I contacted UPS and their website for this tracking number shows that it has yet to be shipped. UPS created an investigation but I'm still on hook from Verizon for the old iphone. Need help.
