In reply to:
some info i have been told by O2 isnt true at all which doesnt say much for honesty on there support.
That's a bit strong!
If you haven't already learnt that first-line support are often clueless at all ISPs once you have rebooted and changed filters then you are going to get very annoyed very often.
At least they were correct in saying the MAC was invalid - and there is nothing they can do about that. Are you saying that Plusnet support were being
dishonest when they said there was nothing wrong with it? What about when they told you that you would have to wait till it expired - which James has now shown to be, choose from:-
incorrect;
mistaken;
untrue;
a lie.
I would actually say "normally the case".
