If that's the relevant company, you should send a written demand for a refund of your payment. The letter must be addressed 'To the Company Secretary' and clearly show both your own name and address and that of the company. It must also include the date and a statement that, if payment is not received within a stipulated period of time (I suggest 21 days), you will commence legal proceedings. You should send the letter by recorded delivery, retaining a copy for your records.
If you don't get your money back (or receive the camera, if that's still acceptable to you), commence legal proceedings. The easiest way to do so is to use HM Courts' Service's online system:
