The Classy Guesthouse not so Classy

I wanted to extend my visit at the Classy Guest House and was told that if I pay R1500 cash, it would be cheaper than going through Booking.com. I can stay another 3 nights. I paid on Friday and on Saturday was asked by a gentleman about my payment. I told him it was taken care of, and I went to my room. Sunday morning, he asked me again about the payment. He became aggressive and told me that if I didn't pay the R1500, he would kick me out. I paid another R1500 in cash, and he then asked for my room key. My belongings were still in the room. He was aggressive and threatened me, so I decided to leave. The lady at reception took my hand and led me away and sneaked me back to my room and told me that we needed to quickly pack and she would sneak me out again. I needed a place to stay for the Comic Con Convention. So I figured I'd only be there at night, but never again. The first opportunity this place got, they ****** me of R3000. And because it was cash, they refused to give me a receipt as proof of payment. I spoke to Micheal at Booking.com on 02 October 2024 @07h52. He placed me on hold and told me that the property agreed to refund me the R3000 and refund the R2654.55 that I paid for my stay. I also spoke to Mohammed A. from Customer Service on 04 Oct 2024. Today Customer Service agent Christine M kept me on hold 47 mins and told me that I can't be refunded Following up via chats and phone calls are pricy since I'm placed on hold 30 mins at a time - I just want my money back. Conflicting stories and photo evidence that the place is dodge and Booking.com does not want to do anything.
