The other answers give good advice on how to present the 2 weeks at this company in future interviews. I won't repeat what they say. 

Instead let's go to the general lesson from this: **you weren't cheated**, what actually happened was you failed to negotiate the deal you wanted.

Let's look at the known facts here

- I was told that they **wouldn't budge** on the salary

- I took a **severe pay cut** taking up this job

And now the hypotheticals & conditionals

- employees were **expected** to get a pay raise in April

- if you **were to** add up the bonus, the annual package **would be** sufficient

Notice how the second list is everything you want, and the first list is everything you don't. You were more *naive* than *misled* here. The deal was what it was. The things you think you were promised weren't really promises, because they weren't written into the contract with specific dates and amounts.

Next time, if you have minimum requirements to be happy with a salary package, be very clear what these are and that you need them written into the contract. 

It's actually win win - if the company truly has the intention of fulfilling promises on future salary they'll of course do that. If they don't, they won't, and you can walk away. Nobody's time is wasted, like it was in this situation. Good luck in your next move!
