While Colín Silva has the option of taking the exam again, she says it costs hundreds of dollars to complete and that is money she and her family cannot spare.

Her family is currently struggling to find the means to pay their rent in Quebec City and to pay for plane tickets to return to Mexico.

Out of money for the retake, rent, or plane tickets back. Sounds like they're just totally out of money.

“I don’t want to speak poorly of a country that welcomed me, but I find this really inhumane,” she said. “It’s as though we are garbage.”

I'm not seeing anything insulting about the government's position. There's a language requirement. They knew that. It sounds like the first test taking may have been free, but on failed tests, the followups have fee. Where are they being treated like garbage?

If they are going to the media, they probably have a hidden motive to do so.
