BT, EE, TalkTalk and Vodafone were Britain's most complained about broadband providers in the quarter from April to June, according to new figures from Ofcom.
The communications and media watchdog said its latest data showed that total complaints numbers were lower than the previous quarter, with the drop linked specifically to fewer issues from customers regarding pay-TV services.
Complaints about broadband, landline and mobile services stayed roughly the same during the period.
Broadband complaint rates
Ofcom's report showed that BT, EE, TalkTalk and Vodafone each recorded seven broadband complaints per 100,000 customers.
BT's figure was flat against the previous quarter, EE saw an increase, while TalkTalk and Vodafone both reported a reduction in quarterly complaints.
Virgin Media was the UK broadband provider to receive the fewest complaints, with four per 100,000 customers. It was followed by Plusnet and Sky, which both received five per 100,000 customers.
Landline and mobile complaints
The biggest reasons for complaints across broadband, landline and mobile services during the period were faults, service quality and getting services connected, the regulator said.
Plusnet was the landline provider which saw the most complaints, with an increase on the previous quarter. A large proportion of these complaints were linked to how the company handled customer complaints.
Sky, Utility Warehouse, Virgin Media and Vodafone generated the fewest landline complaints. Elsewhere, O2 and Sky Mobile were the mobile providers who generated the most complaints.
Pay-TV and response
The most complained about pay-TV providers were EE and Virgin Media.
A Virgin Media O2 spokesman said: "Two years ago, with Ofcom's complaints data showing Virgin Media and O2 at or near the bottom of every category, we drew a line in the sand and committed to fixing our customer service for good."
"While we still want to go further, today's data shows that Virgin Media recorded the fewest proportion of complaints of any broadband provider, while also achieving further significant reductions across TV and landline."
