EE has topped a list of the most complained-about broadband and phone providers. The UK's largest mobile operator has ticked users off the most, receiving the most complaints from customers between April and December last year, according to Ofcom.
Virgin Media had the least amount of complaints, followed by Sky - while customers aired an above-average number of grievances with Plusnet, BT, TalkTalk and Post Office HomePhone in 2014.
Ofcom's study showed that EE had 0.42 complaints about its broadband service for every 1,000 customers with provision and service problems. Issues with switching providers and line faults were cited as some of the other big annoyances to subscribers.
EE also led the way for complaints from pay-monthly mobile customers between January and September, though Vodafone picked up the wooden spoon during the final quarter. Tesco Mobile fared better, receiving the least number of complaints from customers.
A spokesperson for EE said in response to the survey: "We have a comprehensive programme in place to improve service and reduce complaints - and this is borne out by the Ofcom data from last year. We know there is more work to do."
Ofcom's study also looked at pay TV providers, finding that BT TV had the highest volume of complaints - five times the industry average at 0.15 per 1,000 subscribers - while Sky was the least complained-about firm with just 0.01 for every 1,000 customers.
Ofcom director Claudio Pollack said: "Complaints figures help inform consumers' choices of telecoms and pay TV services. There are now more providers included in our report, so people can compare complaints figures for all the biggest companies."
