The Brazilian telecoms regulator Anatel is bringing in new rules for mobile operators from February 2008 in an attempt to reduce customer complaints and improve the quality of services, writes BNamericas citing local newspaper Agencia Estado. The watchdog is keen to place more emphasis on operators’ fulfilling their duties and on protecting consumers’ rights. Under the new rules operators will be obliged to extend the validity of pre-paid credit to 180 days (pay-as-you-go users account for around four-fifths of the total market) from the current maximum of 90 days. Furthermore, if customers have unused credit after the expiry date operators must revalidate it when they buy a new card. In addition, any cases of wrongful overcharging by operators must be rectified with a refund of double the amount overcharged. Consumers will also have the right to pay in instalments for calls charged more than 60 days late. At present this rule is only applicable for calls billed more than 90 days late.
