Rainbow Properties a very big no no

I made an application for a rental, Documentation was send to me, completed everything and I enquired a few days later regarding the application as I had to give notice, on whatsup she informed me, "yes you can move in tomorrow, she would have contacted me earlier. The next day I moved with my belongings to the rental and was informed by the the lesser that he did not hear anything from them. He then called her and she said that I was not approved for the rental, that I am very disrespectful towards the lesser for just pitching up there. I told him abound the whatsup message and said to this agent there is a misunderstanding. She just bad mouth me on speaker phone In front of this lesser and my son. Let me put it to your face you should be reported and she be suspended for your very very poor communication and very wrong attitude, I will be buying a house soon but you will not be my agent and I hope the clients in Pretoria North see this review 0/10.
