Terrible service at Guesthouse

On 1 October 2019 I booked two nights stay on Airbnb to stay at De Molen Guesthouse for my mom and I. When we arrived the manager Lisa was not very friendly or welcoming. She was too busy to take us to our room so she gave the key to her daughter (which I believe does not work there), she didn't even speak to us she just unlocked the door and gave us the key. We were not given the cottage I originally booked as apparently the geyser had burst. As we started to unpack and want to put he clothes in the cupboard, we saw the gowns and swimming towels were shoved into the cupboard and mouldy. We then went to the shop. When I later opened the bed I saw that there was hairs and oily food marks on the sheets and dovet cover. We then phoned the manager Lisa to advise her of the Situation and also ask her for the WiFi password which she didn't give to us before. She then came to us at 21H00, when she checked in other guests. She then told us that her staff did not arrive due to Xenophobia attacks and she had to clean, as she is not a cleaner, but she clearly did not clean. The next morning we checked out just before 10H00, then she showed us the cottage we were supposed to stay in. The bathroom was mouldy and there was not even bedding on the bed. We then went back to the office... so we asked her what she was going to do for the inconvenience.... she said " theres nothing she can do what do we expect her to do"? So we said that we want a refund which she said she can't do as the Owners are overseas and she can't give us from her money and get reimbursed. Then she got up and started to raise her voice and shut her laptop closed and said " I am going to ask you nicely to leave my office", and started closing the door's, and said " I can't handle this I'm he going home".

I mean what type of service is this this. I rased a complaint with Airbnb which will be refunding me half of the money back.
