TL;DR: Yes the incident (viewer complaints) occurred and is confirmed by a reporter Carlos Correa working in the CW6 television station in San Diego.
Jim Patton and Lynda Martin the anchors from CW6 News in the AM were talking about a child who accidentally bought a dollhouse and four pounds of cookies. As soon as Jim Patton said “I love the little girl saying Alexa ordered me a dollhouse”, viewers from San Diego started complaining that their Amazon Echo devices had tried to order doll houses through Alexa the voice service that powers Amazon Echo.
Previously, it is also noted through CBS11 televsion station that a 6-year-old Brooke Neitzel had ordered $160 KidKraft Sparkle Mansion dollhouse and four pounds of sugar cookies by the same method. Alexa doesn’t recognize the speaker's specific voice and Stephen Cobb a researcher for IT security firm ESET advises to change the default settings in such voice enabled devices to avoid these kind of occurences.
“All of these devices which record the internet of things will have some sort of website control, some sort of setting, sometimes the setting is on the device that is communicating. So you need to go into these settings and look at what they are, and what you can change,” said Cobb. Cobb says the Federal Trade Commission is already looking into voice-command devices and toys to make sure the technology is safe and secure. For now, he recommends do your research to keep your personal information controlled and protected. “Down the road the technology will be more sophisticated where it will be able to identify certain individuals and register people can access it,” he said.

Referring to Amazon voice Purchasing Settings, after registration of the Alexa device by the owner, voice purchasing is on by default. It should either be turned off to avoid accidental voice enabled purchases such as the ones mentioned above or a confirmatory code should be entered for completion of purchase.
Amazon says shopping settings can be managed via its Alexa app, including turning off voice purchasing and creating a confirmation code before any order.
The company also says any “accidental” physical orders can be returned for free. Source: News anchor sets off Alexa devices around San Diego ordering unwanted dollhouses
