Tens of thousands of Hongkong Telecom customers are receiving extra-large bills after the Government cracked down on its cut-price international rates.
The company has started sending out the bills after the ruling in June that the rates were illegal and anti-competitive.
In some cases consumers made calls to the United States at about $3 a minute - and they are now being asked to pay another $3.80 per minute on calls made months ago.
The company was ordered to scrap the deals and recover the discounts from customers dating back to April.
The Consumer Council said yesterday six complaints had been received. It called for an urgent review of anti-competition rules in telecommunications.
A spokesman said the firm's customers were 'being asked to bear the cost of what is actually a penalty intended for Hongkong Telecom'.
