March 22 (Reuters) - Britain’s telecom watchdog said on Wednesday it fined BT Group Plc’s Plusnet division 880,000 pounds ($1.10 million) for continuing to bill more than a thousand ex-customers.
The investigation by regulator Ofcom found that Plusnet broke a billing rule by continuing to charge a group of customers for landlines or broadband after they had cancelled their service, the regulator said.
Ofcom said that the 1,025 customers were overcharged by more than £500,000 in total.
Plusnet, which provides broadband, landline, digital TV and mobile services, has refunded 356 customers a total of £212,140, which included interest at a rate of 4 percent for each customer, Ofcom said.
Plusnet has also made clear to Ofcom the action it has taken to prevent any future billing errors of this kind. ($1 = 0.8025 pounds) (Reporting by Arathy S Nair in Bengaluru. Editing by Jane Merriman)
