Cable firm and telco Telewest Communications PLC has slammed British Telecommunications PLC’s claims that its unlimited talk package was unlimited, but it now looks as though Telewest may also be bending the truth.

The Advertising Standards Agency lambasted BT on Wednesday over its direct mail advertising campaign that claimed to offer “unlimited free calls.” In actuality, free calls were only allowed at evenings and weekends.

“BT obviously doesn’t know the meaning of the word. In our book unlimited means just that,” said David Hobday, sales and marketing director at Telewest Broadband.

Not only were BT’s calls limited to evenings and weekends, customers were also charged after being on the phone for more than an hour.

ASA upheld the complaint against BT as its advertising was misleading.

But Telewest’s talk unlimited package also seems to contain limitations.
