We couldnt get an orange one unlocked either, it was my misses phone and she had an account for 2 years, yet when asked in the shop could they unlock it the answer was no, when i asked why not they just said they cant do it in the shop anymore, so i rang the customer services and they said they cant you'll have to go into a shop, well i already did and they said no?

Orange are t&ats

Luckily we are both on Three now, people who actually do as their told if you ring them.
