(Reuters) - Telefonica (MC:TEF)'s UK mobile network O2 was fined 10.5 million pounds ($14.49 million) by Ofcom on Friday, with the British regulator saying some customers leaving the provider were overcharged because of billing errors.
O2 initially identified issues with its billing processes in 2011 but efforts to address them were not successful, Ofcom said, adding that over 140,000 customers were overcharged when leaving the firm between 2011 and 2019.
The watchdog said O2 has accepted the findings of the investigation.
