Aquanano 40 Missing Lamp

[History man]

Earlier today I purchased my first aquarium, an Aquanano 40. When I got home I unpacked the tank with the enclosed pump and heater, but unfortunately the lamp was missing. The box appeared to have been unopened or tamped with in any way, so I can only presume that the lamp was never in the box. I purchased the tank from a shop close to Doncaster, over an hour away from my home and consequently it will be very costly and impractical for me to return to the store to discuss this with them.

Has anyone had any dealings with aqua one for rectifying issues? Do any stores sell the lamp and bulb on there own to fit this tank?
