Migration away and access to email

[#1]

Hi,
I migrated away from plus net on the 20th April.  I have had several emails from plus net prior to and after that time regarding my account closure.  Basically I was advised that:
" We'll work out how much you owe at the time you migrate away. If there's a
> charge due we'll take payment and let you know. After this we'll change
> your broadband account to a free dial-up service, so you can access My
> Account if you need to.
"
A later email I recieved after I had migrated stated that-
"We're emailing you to let you know that as your cancellation request has
now been placed. Your cancellation will take place on 04/05/2010."
My problem is that 1) I can no longer access my account (I get an unrecognised username/password) and 2) Anything sent to my plusnet email address get a bounce back saying it cant be delivered.

My understanding was that I would still be able to recieve emails (I know I cant sent them) from my plus net account.
Can anyone advise me on this, any help would be much appreciated.
Many Thanks

So how did you get in here? 
Sounds like they didn't do it right.
I left ages ago and retained a "dial-up" account; emails still work fine (though very little used).

Hi there,
You've got active mailboxes and an active portal login, so there shouldn't be any issues.
If you're still having a problem can you let me know?
