Carphone Warehouse cannot unlock it @Anonymous
The Network has to request it.
Due to the time elapsed if you haven't used the iPhone on the Vodafone Network it's details may have dropped off their systems so id suggest to pick up a Vodafone Payg sim and use it for the required 30 days making calls, texts and using data which will put its imei back onto Vodafone systems and then request the unlock. It's free to unlock.
Or if your still a Vodafone customer then pop your sim back in it and use If to make calls, texts etc.
An iPhone is not unlocked via inputting an unlock code but instead is unlocked via Apple and their Database.
Vodafone would email you to confirm it's been requested after accepting your unlock request. (Check Spam Inboxes too)
Apple then can take occasionally approximately up to 30 days sometimes to complete an unlock request made by a Network.
Periodically insert an active Non-Vodafone Sim Card in the iPhone and hook up to iTunes.
From the iPhone 5 onwards there's not normally the need to hook up to iTunes to complete the process.
