Found this post about how to get a box and how this guy went about it.

I had a contract with Three for a mi-fi device (as a backup) after the 18 months contract was up, I had to phone 3 times to cancel it....they wouldn't do it. I also wanted to unlock the unit and I had to send it back to them because whatever code they gave me it didn't work. They even told me to go to a Three store that they would unlock it there and then, the manager from the store was non plussed and told me they don't do that kinda service.

Also when I rang the third time to complain about how I was treated they had the cheek to 'hit' me with yet more offers to keep me, was told I was liar that Samba Mobile doesn't exist (it actually runs on their network as a MVNO) when I told them I'll be using that instead of their sim. I had one of their managers (using that term loosely) calling me back and promised me a credit £20 as a gesture of goodwill. Once I received my final bill, that never materialised. Wrote a letter of complaint just to receive a phone call (despite me asking them to write me back) and the guy was saying they never promised me £20 credit, I told him 'yes I'm a total moron I must have dreamt it', just had enough put the phone down and reminded myself to never ever get anything from these buffoons again.

In reply to a post by mr_mojo:

Emailing [email protected] or w/e it is has sorted all my problems out though with them. They refunded all my payment method charges, set the DD up and gave me a free month's service as soon as I emailed them.

As long as things have not changed it IS called the Executive Office, and to my knowledge is still based in Glasgow, as it was when I had the misfortune of working for them. If you think dealing with customer service as a customer was bad, try doing it as an employee. Our "store support" used to go to Glasgow, but that was moved out to Mumbai/Pune where their call centres are... it was like hitting your head against a brick wall sometimes.

I have wowed NEVER to buy a contract with 3!

On a small separate note I am still waiting for my T-Mobile/EE Signal Box to arrive after they removed a local transmitter which has resulted in me having little or no signal at home. Suffice to say, nearly a month later I am STILL waiting for it.
