I too am extremely frustrated by Orange/EE. I am close to the end of my contract and have asked for my phone to be unlocked using the official procedure on the EE website. I need my phone to accept a different sim as I am going to an area of poor orange signal. I als want to swith to a lower tariff while I wait for the 6 to come out.
It has been more than 20 days since the request, so they are in breach of the their own terms. I have spent hours on the phone with different advisers, who make outragous claims bordering on lying. Several examples- it will be done in 72 hours (it wasn't). -it is 20 busines days (it doesn't say that). -you can't unlock an orange phone with the EE web form (not true - it quite cleary states how to unlock orange phones). - will will call you back on a certain day (doesn't happen). I could go on.....
I think that Mr Gillespie is incorrect as EE quite clearly states how they will unlock your phone- this is therefore a contractulal obligation if their terms are satisfied, it may not be criminal but certainly it is a contract and thus illegal not too honour it.
If this phone is not unlocked, I will be putting my evidence to the regulator.
Recently, I have had endless problems with my contract (which was a joint ipad, iphone one) with different people saying different things and making things incredibly complicated. Originally, I was going to upgrade with EE/orange but now after this experience I am going to leave at the end on my contract.
