I have been with Plusnet now for a while.
When I first subscribed I was on a 2mb line with 4gb download usage no free modem.
I then got upgraded to up to 8mb which was great but my line does not support those speeds anyway (bummer!).
Anyway my internet was really slow and I had been unable to send photos via email etc etc. I contacted Plusnet who told me I was over my usage amount (4gb) which I was. But the package at the price I am paying (£14.99pm) on their site says that the download limit is 8gb. I was confusd surely I would automatically be moved to this as my speed changed. Aparantly not!
I raised a ticket to them and they have moved me to the correct plan now.
Up to 8mb
And now you get a free 1 port wireless router (£5.99 P+P BT VOYAGER 2091). So I managed to get this as well!
So anyone on Plusnet I would check your accounts and make sure you are getting what you are paying for!
