Going nowhere slowly

I do not understand how companies like this establishment still get away with this nonsense. I had a conversations before the bill was paid negotiating my terms not the payment. All was agreed upon and then I paid and arrived....different story all together. Not only was the shared accommodation I was first giving dirty from the kitchen to the room but there were empty boxes all over. Fair enough they assigned me to a different room but this room unlike the messy room I was assigned had 4 beds instead of two. I asked if they planned on having four people in said room and they said its a possibility...how when this is not what I asked for and what I asked for was so dirty it wasn't livable. Then I had to deal with two ladies 10 years my senior who clearly wanted the space to themselves but couldn't afford to pay for it in that capacity and finally I confronted their passive aggressive behavior only for them to get upgraded (way to reward bad behavior). I could add to that but let's not digress. Again I asked about potential newcomers and was told 5 people will be moved in (okay no problem) 3 of which will be in the bedroom I am assigned (PROBLEM) with four other bedrooms in said apartment what's the plan here other than to keep going against what was initially discussed before money was taken. I then said if this is what is going to keep happening let's call it a day and give a refund cause it will not work only to be told the refund will take a long time if I even get one. I was fine with the loud weekends, the drilling every day, being interrupted while communicating with staff members, being told that certain guest will simply go to the owner if they don't get their way but this is getting out of hand and it needs to get sorted ASAP. I am so tired of being told I'm being done favors when I paid what they said they wanted and am not staying here for free. Favors are NOT being done.
