I know the problems only too well and too my cost with Tiscali. At the moment ISPs have become such a big market  so very quickly and each trying to grab a piece of the action by fair or foul means its a case of  finding one that will suit your needs best but I know, as I have already said, to my cost its not Tiscali. I have actually sent a strong letter to their Chief Executive Officer at their head office laying out my experience of trying to exit Tiscali and reminding them it is against ISP policy not to provide a MAC code when the customer asks for it(within 5 Days). What I will say is never lose ANY letters or documentation you receive from any ISP as this is what I used to fight Tiscali as they denied all knowledge of letters and cancellation. I eventually got them to admit they were wrong but only after a lot of copying scanning  typing and being threatened with debt collectors  and me contacting OFCOM then I got a an email to say I was right and a rather offhand apology. Personally I think the work I did to sort out their problems (I didn't cause the problems!!) is worth more and that is what prompted me to take it to their CEO. I wouldn't nor could I recommend Tiscali to anyone. The fact is in the circumstances I warn people  away from more trouble but I can only speak as I found. You maybe know differently but you can only speak on your own experience.
