I sent my iphone 6 plus in as they offered £250 for it. Zero problems until they said it was still locked. I followed the email which would help me take the phone off my icloud account and contacted Vodafone to unlock it. After doing all this I had not heard from them for 10 days. I contact them and they came up with some rubbish about how busy they have been. The next day I receive an email saying its still locked. I sent them the email from Vodafone plus a screen shot of the icloud account to clearly show them its all sorted. 4 days later still not heard anything. Email them and phone them. The answer is still the same ( still locked ) so I ask them to send it back to me so I can check and sell somewhere else. Now I have to wait 4-7 days for them to return it to me. Not worth the Hassel
