Help,switching to another provider

[#1]

My contract is up and I haven't got the best picture of what happens next if I want to leave.
Say another provider has much lower prices and I decide to go with them.If the new provider says they don't need a MAC key do I have to get it anyway?
Will the cessation charge apply if I don't , in such a case?Will I have to 'contribute" to the switching process in any way , like giving notice to Plusnet?
I wish the whole MAC key/counter offer thing could take place through our accounts in the member centre.I hate wasting time being on hold/chating to salespeople on the phone.
You can call me antisocial...

If you don't get a MAC there is a good chance you will be stuck with the cancellation charge on the move to full LLU although you may be able to argue the toss but it will be difficult as all Plusnet will see is that the line has been disconnected
You can't move to non LLU without a MAC

It's LLU.What about letting plusnet know?Do i have to do that?If yes,then where's the ''pain-free" switching everyone promises?

There's always the 'second-to-last resort' of writing in.

I guess I'll have to go that way.Of course I'd pay for signed for delivery cause letters do seem to get lost in such cases.
