The UK’s telecoms regulator has revealed that T-Mobile has topped its league of contract customer complaints during the three months to the end of March 2013.
T-Mobile generated above average complaints at 0.19 per 1,000 customers, largely driven by issues related to billing and complaints handling. Orange and Three also generated complaints in excess of the industry average.
O2 retained its position as the provider generating fewest complaints at 0.05 per 1,000 customers. The gap between O2 and Virgin Mobile, which generated second fewest complaints at 0.06 per 1,000 customers, has narrowed in recent quarters.
As Ofcom did not receive more than 30 complaints per month about any prepay provider, they did not report on those.
