So my contact expires soon and I am going to jump ship to Orange however there is a problem, my phone is locked to Vodafone. I tried the unlock request form on Vodafone's website but it came back saying the IMEI number doesn't match their records. I was puzzled by this as I had typed it in perfectly, then I remembered that I had my original iPhone that I purchased from Vodafone replaced by Apple after the lock button became stuck. So obviously Vodafone have no record of this phone being sold to me on my account which means I can't request them to unlock it. What can I do?
