FUP
They were taking the proverbial! I complained, quoting the detriment clause and was told by email reply that it wasn't a detriment as it is considered an 'additional service' They also say that they aren't increasing prices and I'll always be able to browse the internet..and never get charged more than I agreet to.'
They then go on to tell me that I can buy a booster for £12.77/month if I want to get unlimited internet!!
