Bad Treatment, Guest shouted at by owner of guesthouse

My detailed experience at Rosenhof Guesthouse in Clanwilliam is as follows: 1. I booked with them on Sunday, they welcomed me on Sunday evening without confirming the rate though they had promised a better rate than bookings.com since I was gonna stay for 12 days. They only gave me a quotation with banking details the following day (Monday, 22H45) and I paid for the first week. They told me they are upgrading me to a double room (which allows for two or even three people). I took the offer and moved there on Monday. They did not mention that the upgrade actually does not include two people. I had a colleague coming to assist on the project from Tuesday night. There never was an issue with him until Friday. They had seen that he is there and when I made the payment of the remaining week, there was no mention of a paying for extra person since we are two and they had seen that as from Wednesday morning (like Karen rightly puts it). Then they changed their mind on Friday after I had sent them payment proof and decided to charge me for extra person (its them who told me am being upgraded to a room allowing max 3 people, that should be remembered ). They had seen as from Wednesday that we are two people and in any case they are the ones who offered an upgrade. I was tempted to challenge but I decided I will just pay anyway. The problem started when they demanded payment and when i was about to pay, they then said they ll now open the room (single room, with bad on poor condition, no extra blankets not even a space to hand clothes on). I then lost my patience however I decided to book myself at a different accommodation. I told her on whattsap how this treatment does not seat well with me. She decided to come emotionally charged and shouted at me (being a guest-records available). I then listed all the issues with her which she rejected all of them. I then left since she had indicated she was taking bookings for the same room I was booked at. She complained about us not leaving the room in a much more cleaner condition, this also surprised me as she had never asked that we do our own cleaning (She called me inconsiderate as I had left a towel on the floor one of the days). I need to understand what does it mean for her that the guesthouse is private, unlike other guesthouses. I shall await other guests' experiences (guests of the same race as myself) to be proven wrong on my suspicion. She still has not refunded the money. Up to today, she never apologized nor sought to clarify why did she ask me to clarify why she felt we needed to just move out.
