Well, after 18 months with Plus.Net, it's time to return to Vodafone, as it's a bit cheaper.
I also dislike Plus.Net's billing system and do prefer to pay before the actual billing date
I liked the fact that PlusNet stopped charging me for an email only account when they introduced their new billing system. I moved from Vodafone to PlusNet a few months ago as PlusNet were a little cheaper overall for the 18 month contract. It will be interesting to see who is cheapest in a year's time when the contract comes up for renewal. I dislike the way that PlusNet LRS is only available for annual contracts so you can't have it just for 18 months..
