Horrible stay at Die Bostokelos and Spa guest house

We were a group of 6 that made a booking for 2 March 2019 at Die Bostokelos and Spa guest house in Vaal Oewer, Vanderbijlpark, through bookings.com. To start with, the place is not as per photos on bookings.com. Not a tv in every room as advertised. Not a private bathroom, with free toiletries, in each room, as advertised. Pool was dirty. Walls need painting. One of the rooms had 6inch nails sticking out the wall. Light fittings in 2 of the 3 bedrooms were not working and had no globes. The desk-lamp in one bedroom had exposed electrical wires which we had to ask to be covered. No glasses were provided in the kitchen. No towels were provided in the bathroom. Shower was not working at all. Very low water pressure for sink and bath. No toiletries as expected in a guest house/spa. We arrived early, paid the full fee for the 6pax one night accommodation and then arranged with owner/manager Jon-Pierre (JP) that we will return late the evening and would need keys to get in. He confirmed that he will be available up to 1am. On arrival at 10:30pm we phoned JP and he told us that the cleaners had left with the keys and he was no longer at the premises. We managed to get into the house as the main doors were not locked and the locked security gate could be opened from the outside. ie No security. The cleaners were supposed to have cleaned the house, but the counter tops in the kitchen were sticky and dusty. Dead insects were lying on the floor. A casserole dish in the kitchen cupboard was still dirty. We informed JP that we were not satisfied and we wanted our money back as we were not prepared to stay the night. JP agreed that he will refund our money the next day (confirmed in WhatsApp) and we left. We are still waiting for our refund. bookings.com has changed our reservation as a no-show, which is incorrect, as we did show up, but were not prepared to stay under the conditions described above which are nothing short of poor, and false advertising at best. We have also escalated the matter to Nadine at bookings.com, but still have no resolution or refund and promises to call and resolve the matter goes unattended.
