A bit of info here about the subject.
With respect Uncle, that is not a website I'd heard of before your post. It appears to be a highly commercial, ad-laden website - not one that I, personally, would choose to revisit in a hurry. And not one that I'd trust to be an authority on anything at all. These comments are purely person of course, based on casual observation, I may be mis-judging them, and/or others may think differently.
But regardless of that website I think we have established that, for whatever reason, EE's administrative procedures excluded tickmike's request. The question as to whether EE had any good
excuse for doing so, or whether other mobile providers would have allowed it, is academic.
One thing I would say is, as a long-term (PAYG) customer of Vodafone, I have never encountered any administrative barriers that compare to Mike's experience with EE.
