Nexus 5X is defective, no replacement under warranty.

So, I have had my 5X for a while, just under a year. I love the phone and haven't really had any issues with it, but over the last few week it was getting really hot when ever I was making phone calls, and would freeze quite a bit.

So Fi Support is allowing me return the phone for a full refund. That's great and all, however it leave me without a phone. And to make matters worse my wife and I are flying out to spend time with her family in Argentina in a couple weeks.

So I guess I have 2 questions.

Is it normal for google to just give you your money back and leave you without an option for a replacement device?

What would be the best way to get a Fi phone to use for the trip inexpensively? I can't really spend 400 on a replacement phone at the moment. International flights are not cheap!
