Booking and Quote errorLS-

I booked holiday accommodation through Lekkerslaap for December 2021. As the procedure are you look through the website for AVAILABLE and AFFORDABLE places, ask for a quote and then you accept the quote and pay the deposit. Easy. Not with LekkerSlaap and Abalone Cottage in De Kelders Gansbaai. After I paid the deposit I received an email from the owner of Abalone Cottage that he is not going to accept my booking as there was a mistake on LekkerSlaap in fees per night and that the actual amount is almost 5 times more than I accepted and paid for. It has been two weeks and he still didn't pay back the deposit but also do not want to accommodate me on the quoted price. LekkerSlaap also just pull up their shoulders by saying it was a mistake and the system send out the quote and no person can be blamed for the mistake. I strongly feel that Lekkerslaap should take the knock and pay the difference, as I declined other quotes when I accepted this one. And the other accommodation that was suitable for us is not available anymore. This would have been the first time in 4 years that I could take my kids on holiday and now we are faced with this. I am truly disappointed in Lekkerslaap for not even trying to fight for their client (me). They just say they will try and look for something else but I won't get it for close to that price in the area we want to go. Then why quote me something they can't deliver? And I paid the deposit immediately when quote was received.
