[Plugin: Contact Form 7] Text area boxes don't look right on page

I am having troubles with a contact form 7 text area fields, they are one over the another instead one per like, and it looks very awful.

You can see what I mean in https://gecompdominicana.com/gecompwp/formulario-de-cotizacion-web/

I tried to modify the CSS class of wpcf7 text-areas adding the class Display: block; but nothing happened.

My entire class for this I think is:

/* Form defaults */
input, select, textarea {
  font-family: Arial, Helvetica, sans-serif;
  font-size: 1em;
  vertical-align: middle;
  font-weight: normal;
  border: 1px solid #dbdbdb;
  outline: none;
  display: block;
}
input[type="text"], textarea {
  background: url(images/newsletter-bg.png);
  display: block;
  border: none;
  padding: 8px 10px;
  border-top: 1px solid #b9bbaf;
  border-left: 1px solid #b9bbaf;
  border-radius: 6px;
  -webkit-border-radius: 6px;
  -moz-border-radius: 6px;
}

Can you see what can I add? or any other way of solving this?

Thanks in advance
