Im assuming your on one of the business rates? I ask because I'm on HomeOffice 2+ (have been with demon for a good 8 years now) and have a cap of 60GB per rolling 30 day period. I've been capped to 128kbps twice now, so I rang for my mac code thinking I might try Be, and they offered me Demon Business 2+ Pro for Â£30 a month, which apparently is a no limits service. Would be nice to get your impressions of the service before committing to a 12 month contract, if you have the time :)
BTW, I also opted out of e-billing at the time, for very similar apprehensions, it is nice to be vindicated.
