Mark Jackson writes "ISPreview reports that 86% of UK broadband users don't understand the usage limits on their service, and nearly one million have reached or exceeded their ISPs limit in the last year. This is important because 56% of major providers are prepared to disconnect those who 'abuse' the service. However, it also shows how damaging bad marketing can be, with 6.2M people believing they have an 'unlimited' service with no restrictions. The UK Advertising Standards Authority is also blamed for making the problem worse by allowing providers to describe their services as unlimited even if there is a usage cap, as long as it is detailed in the small print. However, consumers are none the wiser with over 10 million broadband customers never reading their usage agreements and a further 1.8M not knowing whether they have read it or not. Unsurprisingly 7.5M do not even know their download limit, which is understandable when so few providers clarify it."
