BT Business Broadband down for six days and counting

Anyone else having issues with BT business broadband, particularily
fixed IP service. We have been down sicne the 20th, they say the
problem arose form the bandwidth upgrade they did in November where
everyone got doubled. Getting info is impossible, they say it's a
duplicate IP address problem and they will try patching tonight, but
they can't say this will fix it. So if it doesn't work tomorrow,
that's a full week
