Trouble with The7 styling /CSS

I have just taken over redoing a work website. I have spent many hours trying to customise ‘The7’ contact form. All the text areas are by default black and I want them to be white. I have ensured the text area is white in every single appropriate menu and have changed the CSS. Everything else works in the css, except the text area colour. which remain black. Can anyone please help me? https://www.sentfnq.com.au/membership/

This is the code I have used to change the css. Everything works except the background colour of the text areas.

div.wpcf7 {
background-color: #badde6;
border: 2px solid #00b8e7;
padding:20px;
}
.wpcf7 input[type=”text”],
.wpcf7 input[type=”email”],
.wpcf7 textarea {
background:#FFF;
color:#FFF;
font-family:Verdana, sans-serif;
}
.wpcf7 input[type=”submit”],
.wpcf7 input[type=”button”] {
background-color:#FFF;
width:100%;
text-align:center;
text-transform:uppercase;
}
