Lol how is it fraud and why should the fans be reimbursed if she used the money for the intended purpose? Just because Nan's visa was rejected, you don't get your money back! The application was still lodged, therefore the money was still used for its intended purpose. The one thing Chloe and Nan *aren't* to blame for in this whole saga is the visa application rejection. What an entitlement mentality this complainer has.
That said, let me put my tinfoil hat on. It would make more sense if they suspected Chloe and Nan never actually lodged Nan's visa application, and just kept the money for it. It was a weird move to apply for a random visa for Nan when they were already engaged. As mentioned in this thread before it would have been easier, cheaper and more permanent to get married and then bring Nan over on a spousal visa. If you're ready to uproot your life and move countries for your fiance/e, you're ready to get married.
I could see them lying about the first application and using that money to pay for a wedding AND a spousal visa, when they were ready to "try again". If Chloe hadn't pushed her way onto Anthony Padilla's show she and Nan would still have a legion of adoring fans on the edge of their seats, waiting to see if twu wuv would finally win against the heartless bureaucracy. It would have made for some good youtube content.
