Property24 - LadyBird Eiendomme - Belinda van Zyl

I am very disappointed in LadyBird Eiendomme who is part of Property24. I saw a property online and made contact with Belinda van Zyl re a property that was to rent at Summer Place12 situated in 200 Dr van der Merwe Street in Montana Pretoria. She was very helpful at first. She emailed me many photo's. I organized with my son to have a look at the place as we are from Richards Bay. But even before my son went to see the place I told her we will take the place, because we could see from all the photo's this is (our) house. She and her husband spoke about it and she said she chose us for the house. We must just send her our bank statements, pay slips, ID document, which I did. So we confirmed that we will take the house. She also asked that I send a letter from my Boss to confirm that I will carry on working from the house even though we are moving from Richards Bay to Pretoria. I send the letter to her as promised today. I tried to phone her feeling very excited. At first she didn't answer. I then send her a whats up message - she still didn't reply. I then phoned again. She answered saying sorry they now decided to give the house to someone else. I am so disappointed! Because what do we do now? We thought we found a house. Now we are back to square 1. She let me believe that all is in order - I just had to send her the letter from my boss. My husband said they are just there to make money and most probably got offered more rent for the house. They always advertise that they will walk the way with you. But Belinda van Zyl from Ladybird Eiendomme in Montana you can not trust. We prayed for this house and that all will go well and I've put my trust in her. But very disappointed. I would like to know if there is any way I can take this further? I have got emails and plenty of what's up messages as proof. So so so so disappointed. My heart is really sore. :-(
