If you provide a platform, like Viagogo, for people to sell tickets then you should take some responsibility when things go wrong.
But Viagogo seems reluctant to take responsibility for what is happening to people like Letia and Shannon Hauraki, who bought tickets to see Bruno Mars on Saturday night, only to line up, and be told their tickets were invalid.
That means that the person who sold them via Viagogo was doing so knowing they were ripping off the buyer.
Viagogo profits in this scenario, as it takes a cut of the sale price.
Media queries to Viagogo were met with a response suggesting that the Northern Advocate check out the "frequently asked questions" section of its website.
