I'm with Freeserve Anytime and concur that failed connections are a problem. However, the connection speed when you do get through is usually pretty good and better my previous ISP which was LineOne pay as you go. That was very reliable and an acceptable speed, but my usage now justifies a 24/7 package and they don't do one.
I have quickly got used to not having to 'clock-watch' whilst on-line and enjoy knowing that it's all covered for £12.99 a month. Having cancelled my first Anytime account to change username, I can assure everyone that they do give prompt refunds on any unused portion of a month when you cancel.
I tried the 50 hour free trial with AOL before freeserve.... What a load of rubbish!
AOL Connects all right but is soooooo slow. Watching paint dry is more interesting. Add to that the fact that it hi-jacks your computer, you can't use Outlook Express and when you want to disconnect it sometimes spends an extra couple of minutes downloading something you haven't asked for (and can't stop) into your computer, thus removing your ability to decide when your phone line will be available for other uses!.... All I can say is that I cancelled AOL within a week and couldn't uninstall it quickly enough!
IMHO, Freeserve is worth the money and I'll probably stick with it now until ADSL is available in my area (if I'm stil alive!). I wish they'd sort out the connection failure rate though.... It IS a pain in the neck.
