"TalkTalk lost 101,000 customers and suffered costs of £60m as a result of a cyber-attack on the company in October, but said business was returning to normal. The telecoms company said the net loss of customers in the three months to the end of December reflected fewer connections and greater “churn” as customers chose to leave. But revenue increased 1.8% in the period, the third quarter of TalkTalk’s financial year."
