Help desk request forms should be as short as possible. They should only include the most important fields like customer data (first and last name, email, phone number if necessary), a long text field for the customer to describe their request, and a “submit” button.
If your customer service department is more complex and consists of a few teams, such forms should also include a drop-down list where a customer can select which team they would like to contact. You can also add other drop-down lists, but remember that the form should be as short and simple as possible.
