Communications regulator Ofcom has suggested that broadband provider Continental Telecom has broken a series of consumer protection standards.
The watchdog has carried out an investigation into the London-based internet service provider (ISP) and suggested there may be evidence that some of its consumers may have been misled.
According to Ofcom, Continental Telecom had, among other things, used unacceptable sales tactics to get consumers to subscribe, while it also failed to inform subscribers of their right to cancel.
The regulator has issued a notification to the company calling for it to improve its work to comply with telecoms rules.
"Under the notification, Continental Telecom has to comply with the requirements within one month and it has the right during this time to make representations to Ofcom in relation to its findings," a statement from the body added.
Earlier this year, Ofcom revealed it was making a series of changes to improve its Voluntary Code of Practice on Broadband Speeds.
