Tesco Mobile is the least complained about mobile network in the UK, a report from Ofcom reveals.
Tesco Mobile had the fewest complaints in the regulator's latest study into customer satisfaction in the telecomms sector, with less than 0.5 per 100,000 subscribers between January and March 2017.
It's the third year in a row that the network has had the fewest complaints.
At the other end of the scale, Vodafone notched up 17 complaints per 100,000 subscribers to place last in the study.
TalkTalk and Virgin Mobile were on eight complaints per 100,000 apiece, followed by EE and O2 with four, and Three with – fittingly – three.
Ofcom has also published an interactive tool on its website that lets users easily search by service or provider, and to compare providers.
"Our report shows that, for a number of providers, there is still much room for improvement," said Lindsey Russell, Ofcom's consumer group director.
"Phone and broadband companies must take all possible steps to improve their complaints handling and customer service, and we expect this to be their number one priority."
Tesco Mobile was understandably pleased at having the fewest complaints for the third year in a row.
"Offering the best service is something that Tesco Mobile has strived to deliver from the start, by focussing on value, innovation and putting our customers at the heart of everything we do," said Simon Groves, Tesco Mobile's chief marketing officer.
"We're proud of today's milestone moment which is down to the hard work of the colleagues who keep our customers smiling."
