UPDATE ----

HI GUYS, thanks for your answers... removed the re-validation in the PHP and it seems to re-direct to the thank you page... but the email i get is blank (without the $name, $phone, etc...)

new PHP code -

$name = check_input($_REQUEST['name']);
$email = check_input($_REQUEST['email']);
$phone = check_input($_REQUEST['phone']);
$refemail = check_input($_REQUEST['refemail']);

and i have removed the below code.

if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/", $email))
    {
    show_error("E-mail address not valid");
    }

Your code seems fine.

You should first try wrapping the mail() and the following exit() statements in a condition. As it is now, you are attempting to mail and exiting before the HTML get loaded for the client to fill in contact information.

See below:

Your New HTML

<form name="sentMessage" action="contact.php" method="post" id="contactForm">
  <div class="row control-group">
    <div>
      <label style="margin-right:85px; font-size:16px;">Name</label>
      <input type="text" class="form-control" placeholder="Name" id="name" name="name" required data-validation-required-message="Please enter your name.">
      <p class="help-block text-danger"></p>
    </div>
  </div>
  <div class="row control-group">
    <div>
      <label style="margin-right:20px; font-size:16px;">Email Address</label>
      <input type="email" class="form-control" placeholder="Email Address" id="email" name="email" required data-validation-required-message="Please enter your email address.">
      <p class="help-block text-danger"></p>
    </div>
  </div>
  <div class="row control-group">
    <div>
      <label style="margin-right:15px; font-size:16px;">Phone Number</label>
      <input type="tel" class="form-control" placeholder="Phone Number (+974)" id="phone" name="phone" required data-validation-required-message="Please enter your phone number.">
      <p class="help-block text-danger"></p>
    </div>
  </div>
  <br>
  <p>If you would like to refer someone else or if you have multiple e-mail IDs, enter them below</p>
  <div class="row control-group">
    <div>
      <label style="margin-right:40px; font-size:16px;">References</label>
      <input type="tel" class="form-control" placeholder="Email 1; Email 2; Email 3" id="refemail" name="refemail" required data-validation-required-message="Please the E-mail IDs.">
      <p class="help-block text-danger"></p>
    </div>
  </div>
  <br>
  <div id="success"></div>
  <div class="row" style="display:inline-block; text-align:center;">
    <div class="form-group col-xs-12">
      <button type="submit" name="submit" class="btn btn-success btn-lg">Send</button>
    </div>
  </div>
</form>

Your new PHP

<?php
  $myemail = '[e-mail]';

  $name = check_input($_POST['name'], "Enter your name");
  $email = check_input($_POST['email'], "Enter your E-mail ID");
  $phone = check_input($_POST['phone'], "Enter your Contact #");
  $refemail = check_input($_POST['refemail']);

  if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/", $email))
  {
    show_error("E-mail address not valid");
  }
  $subject = 'New Website Lead';

  $headers = "From: $name";

  $message = "
Name: $name
E-mail: $email
Contact #: $phone

References:
$refemail
";
  if ($name && $email)
  { //add a condition that validates the email for sending

    mail($myemail, $subject, $message, $headers);
    header('Location: thankyou.html');
    exit();
  }

  function check_input($data, $problem = '')
  {
    echo $data;
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);
    if ($problem && strlen($data) == 0)
    {
      show_error($problem);
    }
    return $data;
  }

  function show_error($myError)
  {
    ?>

    [HTML BODY HERE}

    <?php
    exit();
  }
?>

Hope that helps.

UPDATE:

try replacing your $header with this:

$headers = "From: $name <nobody@".$_SERVER['SERVER_NAME'].">";

Also, replace the following so we can see why you may be getting blank mails:

if ($name && $email)
  { //add a condition that validates the email for sending
    print_r($message); exit; 
    /* 
         if Name, Email, Contact and References are not set. 
         It mean their name value are not still set in your HTML code
         Note: while print_r is in effect. this page won't redirect. 
         we are debugging. 
         Remove the print_r line after you start getting expected values
         and redirect will work fine.
    */
    mail($myemail, $subject, $message, $headers);
    header('Location: thankyou.html');
    exit();
  }
