Switch Statement C#

Question

Can someone please tell me why my switch statement is not working? In my program I have a text box with the choices of 'Billing', 'Tech Support', 'Retention', 'Customer Service'. My switch statement is saying if that text box is = xxx then show a form I build and hide everything else.

Currently only the billing and other option works?!

<

private void cbDept_SelectedIndexChanged(object sender, EventArgs e)
        {
            string reason = cbDept.Text;

            switch (reason)
            {
                case "Billing":
                    gbBilling.Show();
                    gbTechSupport.Hide();
                    gbCS.Hide();
                    gbRetention.Hide();
                    lbOtherReason.Hide();
                    txtOther.Hide();
                    break;
                case "Tech Support":
                    gbTechSupport.Show();
                    gbBilling.Hide();
                    gbCS.Hide();
                    gbRetention.Hide();
                    lbOtherReason.Hide();
                    txtOther.Hide();
                    break;
                case "Retention":
                    gbRetention.Show();
                    gbBilling.Hide();
                    gbTechSupport.Hide();
                    gbCS.Hide();
                    lbOtherReason.Hide();
                    txtOther.Hide();
                    break;
                case "Customer Service":
                    gbCS.Show();
                    gbBilling.Hide();
                    gbTechSupport.Hide();
                    gbRetention.Hide();
                    lbOtherReason.Hide();
                    txtOther.Hide();
                    break;
                case "Other":
                    txtOther.Show();
                    lbOtherReason.Show();
                    gbCS.Hide();
                    gbBilling.Hide();
                    gbTechSupport.Hide();
                    gbRetention.Hide();
                    break;
                default:
                    gbCS.Hide();
                    gbBilling.Hide();
                    gbTechSupport.Hide();
                    gbRetention.Hide();
                    break;
            }

        }

It seems to me that there is some misspelling in the other options. Check the values of reason before reaching the switch.
