BE CAREFUL! Accomodation ****!

Be careful! Booked through bookings.com at one of their properties and paid upfront for 4 nights, arrived the first night to an unsafe, mouldy and dirty property! Walls had mould, door didn’t lock and my kids feet were black from filth. Towels stained, blinds probably never been cleaned. I complained and they came in and then offered me x2 other properties which were not what we wanted or what we initially paid for. They told me a refund wouldn’t be an issue- only to refuse bookings.com to refund. Now they telling me I’m harassing them after trying to contact and having them ignore all my calls! I must remember the POPI act yet they are ****ming me. We arrived at the property to make sure all our belongings were out and there was a team of cleaners and contractors inside! But we are still paying for this property? We handed over the keys after one night stay, I said I would pay for the one night I stayed there but I want a refund for the other 3 and they refuse.
