The UK’s communications regulator Ofcom has revealed the worst-performing operators in the country, with Orange generating the most complaints for broadband in the fourth quarter of 2012 and BT receiving the most pay-TV complaints.

In the three months to December 2012, Orange generated 0.70 complaints per 1,000 broadband customers, with complaints peaking in October as a result of the company’s decision to withdraw its free broadband offer unless customers also purchased line rental from the company.

TalkTalk came second with 0.33 complaints per 1,000 broadband customers, and BT also generated above average complaints levels at 0.30 per 1,000 subscribers. Sky’s broadband service attracted the fewest complaints – 0.08 per 1,000 customers.

BT generated six times the pay-TV industry’s average number of complaints in the fourth quarter of last year, thanks largely to problems with service provision and complaints handling issues, generating 0.24 complaints per 1,000 customers.
