Massive Upgrade Issues with EE

[WyrmUK]

So... I wanted to change my phone and move over to EE from Orange... seemed like a simple enough thing. to do as they are the same company.
So I called in at the EE store in Victoria station on the way home. They had the Nokia Lumia 920... and I stated I wanted an upgrade. So the assistant starts to put it through as a new contract... after a credit check and some questions about finances etc, one of the other guys mentioned this was for a new number... and so I told him I was upgrading and the process had to start again. However they could only accept cash as the card reader wasn't working... and I had to wait as only one till was working... and then they couldn't do the upgrade anyway as the system didn't work... It was just after closing when I tried to leave, and they'd dropped the shutters... but could they open them? Well it took about 5-10 minutes!
So I phoned the next day to upgrade over the phone - seemed to go ok... phone arrived... but they had sent the wrong SIM (a nano rather than a micro). So I had to phone them up again... and they said it would be with me the next day... well it wasn't and when I rang up again the operator initially said it had been despatched that day, then when I said I was told it was being sent out the day before the started blaming the snow, weather, postal service, oh and they said that they had read the note wrong and it was just a random note!
So the next day the SIM arrives... and I put it in the phone and switched on... and the phone started... then rebooted... and again... and kept doing it until it froze. On the phone again... the operator said I should go to the local EE store who would be able to put in a different SIM and sort it... so off the the EE store where the guy there said what I'd been told was wrong, and that the phone was bricked anyway! Just from putting a SIM in! Back home and back on the phone again... the operator said that apparently EE have been having problems with the 4G SIMs and that they'd just had a note through that day about it and that they weren't activating customers with Nokia 920s over the phone any more... however the forums are full of reports of customers contacting EE about the very same issue from at least 2 weeks before I ordered mine! So I cancelled the EE service and requested a transfer back to Orange. The operator said it would be done the next day and that I'd get a bag to send my phone back in. I rang up the next day and was told that what the previous operator had told me wasn't correct and that I'd have to wait for the phone to be returned before I was moved back! I got the reorded delivery bag to send the phone back in that day and duly sent it back last Friday. When I rang up yesterday I was told that my account still hadn't been switched back and the operator said that the envelope had had the wrong code on so had gone to the wrong place, but it was back and he'd put a note through to have my account transferred back within 24/48 hours... and it would most likely be 24 hours. So I rang up today... and it hadn't been! No surprise there! This operator said that there was no note of the previous day's conversation on my account! He also said that it would be about 5 days before they'd get around to processing it and to ring back Thursday of next week!
To cap it all... I phoned them asking for a PAC Code and they said that despite me having no service... and that the contract is in the process of being cancelled back to Orange (and is marked as such on their system)... and that I'm well within the 14 days cancellation period... they can't issue me with a PAC Code to transfer my number for at least a week (when the contract will have been cancelled - but I'm not holding my breath) without me having to pay a large 'buy up' fee for the EE contract - and can't put a temporary number on the account whilst it's being cancelled to allow me to transfer the number.
