No other industry...
I've been a Telewest / Virgin customer for years, It sickens me that the "fair usage policy" penalises me for using a service I pay for. In my view the answer is simple - OVERSUBSCRIPTION. Providers cannot provide the bandwidth to all their customers on the books - especialy during peak hours - which funnily enough is when most people want to use it - but if I do use it my speeds are restricted by 75% for 5 hours - so not quite unlimited is it.
Other industries wouldn't get away with this - imagine walking into a pub and the price list stating £2.50 for upto a pint of lager - depending on how busy we are you may only get a half.
Someone needs to have a word - I feel like I'm being robbed.
