SAO PAULO (Reuters) - A Sao Paulo resident reeled when his bank rang him over his March telephone bill. It totalled $43 million. "I was horrified," said Nelson Marotti Filho, 42. "My bank called me to ask what I wanted to do with the bill. They usually deduct it directly from my account." After a hasty call the Sao Paulo telephone company mailed him a new, corrected bill for just $31. It was the latest blunder for the company, bought by Spain‘s Telefonica in a trophy privatisation last year. Even Brazilian President Fernando Henrique Cardoso attacked the company on national radio last Friday after regulators found it guilty of cutting lines and switching numbers without notification.
