Bad experience and not getting any feedback on this matter. Going for months now

Very bad experience with lekker slaap. We booked a place it was double booked. We asked for alternative dates. Unfortunately none of the dates was working for our group of people that booked the accommodation. After several of months not receiving a refund. And constantly following up on the refund we only get mails back stating that this has been escalated and still waiting on feedback from the account department. After banking statements that have been sent. Still no refund in my account. Still just mails going back and forth back and forth. With the same reply sorry for the inconvenience and we will get back to you. This is really not how a company should treat any one. Still no refund. I am really not happy with this service or this company
