Unfortunately this type of error isn't something we can easily clear as our systems have stumbled upon a problem when trying to complete your upgrade to fibre in the billing engine, so we'd charge you for fibre rather than standard broadband.
It's flagged up automatically as a system error affecting your account we're aware of and the relevant people will be working to resolve as soon as possible. Really sorry for any inconvenience caused in the meantime.
