Damage deposit refund for Unit3- used on the 9-11 August

Good Day

we booked accommodation for the 9-11 August at Ramsgate Beach club as a group of friends. When we checked out on the 11 August we asked the unit owner Mr Johan who can be contacted on *** as to how long it will take for them to refund us the money we paid as a damage deposit for the unit we used which was Unit 3 and we paid R1000 damage deposit. he said it will be paid out in 10 working days. He gave us a person to contact by the name Milly who deals with bookings and payments. We sent Milly the proof of payment for the damage deposit a week before our stay and she said we will receive the refund within 7 working days. We kept contact with Milly on email on *** she does not respond to any emails regarding the matter she no longer answers our calls on *** she used to answer our WhatsApp messages regarding the refund on *** which she no longer does and her phone is always on voicemail. We are deeply disappointed by the service and all Johan tells us is that the money will be paid eventually. 6 weeks down the line we still have not been paid and are not being given feedback on what the hold back could be. We just spoke to Johan now who said we should involve lawyers when we were merely just trying to get feedback and try to escalate the matter.
