Zelri Properties review: Disappointing experience

I don't know what policy does Zelri properties work with, I applied for accommodation and as a student that stays alone I wanted a bedroom flat and then they said my salary was high so I only qualify for a 2 bedroom apartment. I tried to raise my concern with an agent she said they can give me the 1 bedroom that I wanted but I will have to still pay the same amount of rent as for a 2 bedroom ... it made no sense to me because stated clear that I am applying for 1 person . I have a friend that also applied they are more that 5 and they got approved for a 1 bedroom i did not understand the whole setup . I am disappointed some of the agents are rude and unproffesional . I wish there could be something that can be done with this matter.
