Telco BVivid has paid fines totalling $25,000 for making telemarketing calls to consumers in areas transitioning to the NBN that breached Australian Consumer Law.

The Telecommunications Industry Ombudsman's latest report describes the misleading behaviour of "a small number of retail service providers" and explains what consumers and businesses can do to protect themselves.

The telecommunications regulator, The Australian Communications and Media Authority, continues to clamp down on unlawful telemarketing and breaches of spam laws, with electricity, gas and Internet provider Sumo Power the latest company to be hit with a penalty for infringing the law on telemarketing.
