I received an email containing the following from Plusnet on 14/11/2011
"We have good news for you. The exchange equipment we use to provide your service has now been upgraded, and we can offer you a faster 'upto 20Mb' service.
You don't need to do anything, and we'll switch you over automatically, for free.
We expect this to happen within the next 5 weeks."
I then received the same email again on 20/1/2012. and since then nothing.
No noticable speed increase and no further email. Any ideas ?
