BT remained above the industry average with 7 complaints per 100,000, which is consistent with the last conducted report. Virgin Media, however, has seen a consistent reduction in the number of complaints received, dropping from 6 to 5 per 100,000 to meet the current industry average.
Vodafone joins Tesco Mobile as the least complained-about mobile provider
The best-performing pay-monthly mobile services were Tesco Mobile and Vodafone, with 1 complaint per 100,000 customers, making them the least complained about services. Tesco Mobile and Vodafone are currently the only two providers below the industry average number of complaints.
iD Mobile and Three both saw drops in the number of complaints received. Both services saw reduced complaints from 3 to 2 per 100,000 customers since the last report. However, both providers were above industry average in specific complaint categories.
The biggest driver of Ofcom complaints for iD Mobile was how its customer complaints were handled. For Three, the dominant issue raised in its customer complaints was billing, pricing and charges.
O2 received the most complaints. Despite the total number of complaints decreasing from 4 to 3 per 100,000 according to the last report, O2 remains the most complained-about UK mobile network and is the only one currently sitting above the industry average.
