Asking the institute about the status of the application
I would initially say probably not, however there is no way of knowing for sure.

I am not sure if using strong words is advisable when waiting to hear back. I hope your 'sacrifice' of other positions hasn't left you with nowhere to go. 

For what it's worth, I would try explaining in the future your situation in a way that makes it sound like you need to know in order to make a decision, as opposed to sounding like you are upset with them for not informing you yet. There are often multiple people involved in decision making and it can be hard to get everyone together to decide. 

In other words, I think it may be better to say something like "I have other offers, and would like to know what your decision is before making my final choice" and giving them a solid date that you need to know by.  

Cheers.
