Shock horror! It was Sky that messed up, not Tiscali!
Ordinarily I'd apologise for making such a mistake (blaming Tiscali when the fault lay with Sky). But, as we're talking about Tiscali, I won't. They don't deserve one after the 'service' I've received from them over the last year (and especially the last couple of months). Maybe if they had given me back the money that they took (without authorisation) as swiftly as they took it, I'd consider a reluctant apology. They didn't, so I won't.
Not off to the greatest of starts with Sky. Hopefully this is a one-off blip and not indicative of their service. Last thing I need is the hassle of changing supplier again.
I don't know what was wrong with their system that they believed the code was wrong to begin with. At least now they've accepted it and things should be in motion. Hopefully this hasn't delayed things too much as I've got this lovely Toshiba Tecra M9* laptop here and, as much as mobile broadband is useful, I need ADSL to make the most of it (I've only got the laptop on loan for another two weeks).
