NTL has angered customers by imposing download limits on its broadband service.
According to the BBC, the company's terms and conditions now limit its customers to 1GB of downloads a day, even though the company's advertising says the advantage of broadband is "unlimited surfing".
Users said the limit could be as little as as two-and-a-half hours of downloading a day. One angry customer told the BBC: ""They have said this is the Ferrari of broadband services. But it is no good having a Ferrari if you can only pop down to the shops in it."
NTL said the limit was necessary to help all of its customers get a consistent service, and that the limit is equivalent to "200 music tracks, 650 short videos, 10,000 pictures or around 100 large software programmes downloaded per day".
The company also said that only a small percentage of customers, whose use of the service persistently exceeded normal levels, would be affected.
