<human>: So, this is the story:
On the last days of April I started an internship on a certain magazine (let's say Time Out Mexico, though it might or might not be that one). The teacher who got me the interview, as well as the editor who I was gonna do work for, both mentioned it was a 3 month internship or test period before getting a more "real" position on the magazine (and thus, a pay to go with it), so I accepted keeping that in mind and as a goal of my work there (apart from all the experience, of course).
This morning I met with my editor to discuss my future on such magazine, and the person mentioned that the interns actually have had a 6 months to a year trial period (instead of the 3 months that was first discussed) and that they weren't able to do anything for me right now, even if they were looking forward to hire me in another three months for a more formal position, as well as saying how satisfied and happy was with my work and all that kinds of praises. 
After spending the day thinking about it, I feel kind of discouraged about the reaction and I feel like I've been lied to, up to the point where instead of keeping my intern job I feel like just quitting for good. I've been thinking of sending an e-mail (since it's easier for me) to my editor, telling this person about such feelings and how I think I've been cheated on with the time change, though I don't really know what's my position on this and since this is my first job, I figured I might ask for your help on this one.
As I mentioned, one of the reasons I even started with the internship was the fact of getting paid (after three months they said) and I don't really feel motivated to keep doing this for three more months, since it's not really profitable for me at all (mostly because I'm paying for everything). What can I do to express my feelings to the editor, keep my job and get paid? What's the limit I shouldn't surpass when expressing this feelings? Can I express my resentment to their lie (because that's what I was) about this internship?
Once more, thank you all?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I was up for a 3 month internship that ended and was just told that it was actually a 6 months to a year one, so I need to wait more time if I want to get paid)
