I'm still with tiscali and i've not been able to connect since last tuesday. I called them that evening and there was a message saying there was an outage at the exchange in Brighton. Since i live about half an hour away, i assumed that was why i couldnt connect.
24 hours later i still couldnt connect, and that same message was still on their helpline but i chose to speak to an operator to confirm my problem was connected to that outage. They said it wasnt. They did all sorts of tests and said they'd get an engineer to call me the following day (Thursday)
On the Thursday afternoon, an engineer called me, he did more tests and found that the line is "stuck". He said he'd get BT to go to the exchange to fix the problem and that it would be resolved within 24 to 48 hours and that someone would call me to say it was resolved. Just to confirm again, i asked him to check that there wasnt still an outage in Brighton. He told me that no exchange existed

Saturday morning, still no connection and no phone call. Saturday evening I called Tiscali from work and i was told there was no fault and no record of any faults. I went mad. He then read my "elevated records" or something like that and found the fault history. He said someone would call me back and asked me when i'd like this to happen. I said 6pm the next day. Half an hour later, i miss a call on my mobile from tiscali. I called them back on the customer care line, asking them to try calling me again. They said they'd ensure that happened, but it didnt.
Then at work today, i find an email to my tiscali address sent yesterday, commenting on the fact that i missed a call at the specified time. The specified time was 24 hours later

I just called them and apparently BT have thrown the fault back as invalid as tiscali havent instructed me to take one final step, which they've told me to do and i'll do it when i get home.
Deary me, the service is f***ing rubbish.
BTW the error message i get is "Disconnected. Error 721.." Cant remember the rest of what it says, but i've googled the message, and what i've found is VPN error messages, but i'm pretty sure my error message doesnt mention VPN
