Well as for email notifications. NTL have long since stopped sending me emails notifying me of my direct debit payments. They were like clockwork at one time - every month my email arrived telling me how much was due. But not had anything like that for months.
So I think it's safe to say I haven't had anything at all mentioning upgrades. Have to say I did have an amusing chat with some indian chap when I called tech support about downgrading (I didn't realise you called CS) anyway, he told me he could switch my speed down but would need to keep charging me the same amount each month as for 10meg and was that any use to me
yeah, ummm, that would have been wicked - thanks!
