LONDON, Oct 26 (Reuters) - Britain's telecoms regulatorOfcom said it would fine Vodafone a record 4.6 millionpounds ($5.60 million) for customer failures, including notcrediting accounts when mobile phone users topped up.
The regulator said Vodafone also failed to act quicklyenough to identify or address the problems, which stemmed fromthe company transferring to a new billing system.
Some 10,452 customers collectively lost 150,000 pounds overa 17-month period between the end of 2013 and April 2015, Ofcomsaid on Wednesday.
Vodafone said it deeply regretted the system and processfailures and had refunded the vast majority of customers.($1 = 0.8220 pounds) (Reporting by Paul Sandle; editing by Kate Holton)
