I created a simple page with list box and text area with conditions that all should be required.
List box are working fine, but textarea box doesn't tell that the field is required to be filled.
<!DOCTYPE html>
<html>
<head>
<title>Ratings & Reviews</title>
<body>
<form>
<span>Customer Service*</span>
<span>
<select name=customer id=aa required>
<option selected="rate" value="" disabled>rate</option>
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
<option value=4>4</option>
<option value=5>5</option>
</select>
</span>
<br><br>
<span>Value for money*</span>
<span>
<select name=money id=aa required>
<option selected="rate" value="" disabled>rate</option>
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
<option value=4>4</option>
<option value=5>5</option>
</select>
</span>
<div>
<textarea name="reviews" rows=11 cols=50 maxlength=250 required>
</textarea>
</div>
<div id=submit>
<br>
<input type=submit name=submit value=submit>
</div>
</form>
</body>
</html>
You have empty space inside text area, remove it:
<textarea name="reviews" rows=11 cols=50 maxlength=250 required ></textarea>
